Fashion Faceoff: Dianna vs. Emily

DIANNA VS. EMILY

The colorful print on this Osman dress is so pretty we like it equally as a gown (on Dianna) and iin midi form (on Emily) . So we're very curious to see which way you vote.

KARLIE VS. KIM

The supermodel (who told PEOPLE she had her Tamara Mellon "Sweet Revenge" legging boots custom-made to fit her crazy-long stems) wears her custom pair as pants. Kim, on the other hand, layered the $1,995 bottoms under a leather skirt.

MEGAN VS. BEYONCÉ

After you vote, the next decision you have to make is whether or not you're willing to spend $154 on this Bella Dahl chambray top because of how cute it looks on both Megan and Beyoncé.

MELANIE VS. JENNIFER

There's 15 years between them, but the 57-year-old actress definitely holds her own against the 42-year-old star in this sheer-paneled Stella McCartney gown.

SARAH VS. TARYN

Hollywood is like one big crop top convention, so of course the Modern Family star and the Orange Is the New Black actress have the same Alice + Olivia style.

MAYA VS. KERRY

We don't know what's more surprising: The fact that this Stella McCartney dress costs close to $3,000 or that it's sold out.

PALOMA VS. EMMA

The singer adds a pop of color to the black Lanvin design via her shoes. The actress, however, keeps her whole look a deep, moody black (except for her red pout!).

CAMILA VS. ALYSSA

Both celeb moms clearly both love ruching (as seen on their Dolce & Gabbana dress). But their similar taste stops at the corset. Camila drops the waist-cincher to show off her cranberry frock, while Alyssa embraces the accessory on her emerald green version.

ISABELLA VS. CARA

This look goes immediately into the "Things Only Supermodels Can Wear" folder you keep on your desktop. What? You don't have one of those yet? Then this bold Balmain jumpsuit – surprisingly sported by two people – can be the first photo you add to your new one.

ASHLEE VS. JILLIAN VS. MARIA

"Marsala" may be the Pantone color of 2015, but these ladies are getting a head start on the trend with their DL1961 skinnies. And we have a feeling a lot more stars will be following suit.

ALESSANDRA VS. KENDALL

As soon as we saw this super-sexy dress on the Victoria's Secret Angel, we knew it looked familiar. And that's because Kendall debuted the look on the Balmain runway. We don’t know who will win this Faceoff, but we're positive you have to be a supermodel to wear this.

SOLANGE VS. JENNIFER LOPEZ

It might take you a few seconds to actually see the Faceoff taking place here. And that's because you're probably distracted by Solange and J.Lo's abs in their criss-cross Milly crop tops.

Fashion Faceoff: Dianna vs. Emily

GIGI VS. RITA

The model teams this bold, beaded Emilio Pucci mini with simple, sleek sandals. As for the singer, we don't think the word "simple" exists in her style vocabulary. She teams the same design with studded statement shoes.

OLIVIA VS. JENA

That's a whole lotta skirt to pull off, but neither Olivia nor Jena seems intimidated by the voluminous Emilia Wickstead design, which they style completely differently.

ERIN VS. CAMILLA

The neckline on this periwinkle Gucci gown is so stunning, it needs to be seen. And these stars definitely agree with us, both opting to wear their hair up to show off the silver detailing.

EVA VS. VICTORIA

Coat envy, anyone? This chic white topper from Posh's own collection will cost you close to 4k. And we're going to add it to this list.

BELLA VS. BEYONCÉ

White jumpsuits are like the new LBD (see here and here), so it's no surprise these two stars own the same Gucci design. But will Bella knock Queen Bey off her throne? Vote to find out.

ANGELINA VS. FAN

The Oscar winner made a few tweaks to this Ralph & Russo design, while the Chinese actress wore it the same way it appeared on the runway.

KHLOÉ VS. PORSHA

There might be a third person to add to this Constantina and Louise gown faceoff between the two reality stars, because we all know how much the Kardashians love to share their clothes.

JULIANNE VS. CATHERINE

It's not every week two seasoned screen actresses faceoff in the same-style Louis Vuitton dress. Once you're done being amazed by that fact, you can go ahead and vote for your fave.

TAYLOR VS. JESSICA

If we told you two of Hollywood's hottest style stars were wearing a Talbots bunny-print sweater, would you believe us? We've got the photo evidence. The sweater is sadly sold out, but as a consolation prize, you still get to decide if it looks better with skinnies or boyfriend jeans.

Fashion Faceoff: Dianna vs. Emily

NAOMI VS. BEYONCÉ

There's a lot that these two fierce divas have in common, including this mosaic-embellished Tom Ford dress. However, the supermodel adds some length (and a fur boa) to the original design, while the superstar sports the look the same way it appeared on the runway – from the mini style to the matching boots.

VIDA VS. EMILY

Of course, we'd never actually pit a 4-year-old against a 31-year-old in a style showdown. We just couldn't resist showing you how cute this Dolce & Gabbana floral dress (as seen on Matthew McConaughey's daughter and Emily Blunt) looks in miniature form. Like, crazy cute.

NIKKI VS. JAMIE

When two Celeb Style Council members go head-to-head in this gallery, you know it's going to be a tight race. You also know you're probably going to end up buying something. Nikki styles her Bebe metallic tweed jacket with black jeans and ankle boots, while Jamie takes a preppy schoolgirl approach, teaming the topper with a pair of shorts and patent loafer pumps.

Fashion Faceoff: Dianna vs. Emily

ANA VS. EMILY

LBDs with illusion paneling are hanging in every celebrity closet, so it's no surprise these two stars stepped out in the same curve-hugging Gustavo Cadile design. And since they're both wearing strappy black sandals with it, you might have to make your decision based on the down vs. up hair debate.

Fashion Faceoff: Dianna vs. Emily

ALEXA VS. JENA

The British style star chooses to keep some things a secret – like the color of her underwear – in this Valentino dress. The Hunger Games actress, on the other hand, isn't shy about baring her black briefs and matching bra.

ROSIE VS. RIHANNA

Designer Tom Ford recently revealed that the pasties in his latest collection (as seen on this white gown) were inspired by "very young women who have the bodies to pull it off." Clearly, both Rosie (at a photoshoot) and Rihanna (on the red carpet) meet this description.

EMMY VS. JORDIN

We'd recreate the Shameless star's look for brunch, and we'd probably recreate the singer's take on the same 7 for All Mankind denim for date night. To which event do you want to wear these jeans?

Fashion Faceoff: Dianna vs. Emily

MICHELLE VS. BAR

What do both stars have in common (aside from being fans of this Georges Chakra Edition dress)? The confidence to show off their legs in daringly high-slit skirts.

Fashion Faceoff: Dianna vs. Emily

CARA VS. HEIDI

Fanny pack enthusiasts will probably like the casual-cool way Cara styles her ripped Dittos skinnies. If fanny packs confuse you, you're more likely to appreciate Heidi's more straightforward approach.

Fashion Faceoff: Dianna vs. Emily

KYLIE VS. RIHANNA

These stars have a lot in common. They like to change their hair all the time. They've mastered the art of a good pouty-face selfie. (See here and here.) And they both have this sexy Alexandre Vauthier satin gown hanging in their closets.

ALEXA VS. SARAH JESSICA VS. ROSIE VS. CARA VS. OLIVIA

Even if you're not a poncho person, you have to admit this Burberry monogrammed style (as seen on just about every fashion It girl) is super-chic. And if you are a poncho person, bad news: It's sold out everywhere.

KIRSTEN VS. NAOMIE

At first glance, you might think these are two different dresses, but they're actually the same. Kirsten shows a bit less skin, tailoring the bodice on her sea foam Burberry Prorsum design, while Naomie decides to keep things sexy and bare her sternum.

JAMIE VS. BRIE

Okay, the hair award goes to Jamie (have you seen her style from the back yet?). But it's all about who makes you starry eyed in this printed Diane von Furstenberg dress.

JAMIE-LYNN VS. EMMY

If you heart N.Y.C. enough to wear it on your dress (like these ladies do in their Elie Tahari for Kohls design) you only have to spend $42 on one for yourself, and then you can join this faceoff.

Fashion Faceoff: Dianna vs. Emily

AMBER VS. DIDDY

This Eleven Paris "Biggie" sweatshirt is advertised for men, but that doesn't stop Amber from owning the look. Now you have to decide if you'll be adding the $78 topper to your holiday wish list (or buying it for your boyfriend).

GWEN VS. BEYONCÉ

We can't imagine who other than Gwen and Beyoncé could pull off these R13 plaid shorts (featuring a built-in shirt tied around the waist), but apparently a lot of people are trying. The $495 bottoms are currently sold out.

Fashion Faceoff: Dianna vs. Emily

KIM VS. KHLOÉ

Thanks to that low neckline and thigh-high slit, we have a feeling this silky draped Lanvin gown will continue to rotate to other Kardashian closets. (For the record, Khloé wore it first. And we're guessing Kris will wear it next.)

JENNY VS. HILARY

We certainly wouldn't guess that these two stars share the same taste in dresses, but as it turns out, the flattering silhouette on this embellished blue Peter Pilotto design works well on both of them. There can still only be one winner, though, so vote below!

GIGI VS. ITALIA

The model-approved way to wear this Lovers + Friends jumpsuit? Add a draped moto jacket and sleek strappy heels, like Gigi. Or you can ditch the jacket and play it up with metallic accessories, as the Canadian actress demonstrates.

MARIA VS. OLIVIA

JENNIFER VS. KRIS

Like many stylish moms, the matriarch of reality TV borrows a dress or two from her daughter's wardrobe … but is it possible that she's raiding Jennifer's closet (for this Valentino mini) as well?

KIERNAN VS. HARLEY

We can't blame the model-slash-DJ for mimicking Kiernan's style – especially since the teen star is on PEOPLE's Best Dressed list! But we love that each star gave her quirky Tanya Taylor skirt a distinctive spin.

HILARY VS. ELIZABETH

How do you make any outfit look cooler and more fall-friendly? Both Hilary Duff and Elizabeth Banks know the secret: just add a black leather moto like this killer one from J Brand (which also comes with a killer price tag: $1,195).

EVA VS. REBECCA

These silk printed Campbell Brand pants seem like a tough piece to accessorize. But both Eva and Rebecca flaunt the bold pair with three-quarter-sleeve tops and pointy pumps.

SELENA VS. LUCY

The LBD? So last week. These ladies are making the LRD happen, big time. But since there can only be one Dior darling, we suggest you make this decision based on whose shoes you prefer.

LEA VS. CASSIE

What do you need to pull of this daring velvet Cushnie et Ochs dress (aside from an ah-maz-ing bod)? A whole lot of attitude, which both stars clearly have in spades, judging from those sexy "I-know-I-look-good" gazes.

LILY VS. NOOMI

Sure, a great suit will always be in style, but we're not sure whether these ladies will be able to recycle this memorable Emilio Pucci number. (Perhaps they could lend it to friends to expand the Fashion Faceoff circle?)

TAMRON VS. IGGY

It's hard to imagine a Today Show host and a "Booty"-licious rapper ever stepping out in the same outfit. But it happened – in this $1,550 mosaic-print Givenchy design.

VICTORIA VS. KIM

First it starts out with Posh and Kim wearing the same clothes (like this leopard-print Balmain pencil skirt). Next thing you know they'll both be arranging front-row Fashion Week play dates for Harper and North. (Hey, it could happen!)

LINDSAY VS. NAOMI

In LiLo's world, you can never wear enough sparkle – thus she teamed her iridescent sequin Givenchy midi dress teamed with blinged-out Christian Louboutins. Naomi tones things down a bit, wearing the same sparkly dress with neutral sandals.

GWEN VS. KENDALL

There's nothing basic about a girl whose favorite pair of jeans is a tuxedo-striped skinny style, which explains why both the singer and the model have these 7 For All Mankind bottoms in their closets.

CHIARA VS. CARA

Bra or no bra? Bedazzled mouth jewelry or no bedazzled mouth jewelry? The Blonde Salad blogger clearly plays it safe – well, safer – while the supermodel goes all the way in her lace Burberry Prorsum dress. (Though on second thought, is that enough fabric to legally be considered a dress?)

LARA VS. DIANE

The best accessory for this mod Christopher Kane mini? Great legs, which both the model and the actress clearly have. So you should probably make your decision based on which color accents you prefer: pink or blue.

FERGIE VS. JAY Z

You'll find this $405 Rodarte jersey in the women's department (as seen on Fergie), but that doesn't stop Jay Z from owning the look with some serious confidence. (We wonder if he swiped it from Bey's closet?)

Fashion Faceoff: Dianna vs. Emily

CARRIE VS. KELLY

This dramatic Jacob & Co. diamond spiderweb hand jewelry (as seen on the singer and the TV personality) definitely belongs on the stage. It also belongs in a safe, due to the $67,700 price tag.

Fashion Faceoff: Dianna vs. Emily

ANNA VS. DIANE

The Vogue Japan editor's Mary Katrantzou badge-adorned dress may be insanely busy, but that doesn't stop her from adding colorful platform sneaks to the mix. The actress takes a more subtle footwear approach with sleek Stuart Weitzman sandals.

PEYTON VS. OLIVIA

You should take one very important thing away from this Faceoff: The urge to buy a jean skirt for fall. Want theirs specifically? Peyton and Olivia are both wearing one from Black Orchid.

JANUARY VS. ELLE

These Ström "Femton" boyfriend jeans have everything we love in a pair of jeans: comfort, style and that "wear 'em every day" look (clearly, both actresses have the same taste as we do).

NICKI VS. OLIVIA VS. EMMA

We're still having a hard time believing that all three of these stars reached for this same Valentino dress, but we also must admit that they each give it their own distinctive spin. Good luck deciding whose take is your favorite.

ANNA VS. LUPITA

First, vote on these two stars in the same palm-tree-printed blue Fausto Puglisi mini. Then decide if you're more envious that the Vogue Japan editor-at-large got to wear hers in Milan or the Oscar winner got to sport her dress in Hawaii.

KERRY VS. TAYLOR

On their hit TV shows, Kerry's usually in neutrals and Taylor's all in orange. Off-screen, however, both actresses like to play with colors. For example, this paint-splattered Sportmax skirt.

Fashion Faceoff: Dianna vs. Emily

JAIME VS. TARAJI

One sheer-paneled Charlotte Ronson dress. Two very different ways to style it. The Hart of Dixie star goes for basic black accessories, while the No Good Deeds actress adds a serious pop of color with a neon orange clutch and matching shoes.

JOURDAN VS. MILA

It takes some serious style cojones to rock a quilted light denim suit. Clearly both the supermodel and singer were born with the same risk-taker gene. (It also takes some serious cash to rock this Moschino design in particular, as the set totals over 3k.)

VICTORIA VS. NICOLE

What's more surprising than two stars stepping out in this Balenciaga cape top? The $1,075 price tag. Even crazier than that? It's already sold out.

DIANNA VS. CAMILLA

Both stars have similar styling ideas when it comes to their MinkPink "The Pianist" dress, which will make it hard to vote. But with a $76 price tag, can we agree that we're all winners?

ALESSANDRA VS. JESSICA

Slouchy track pants are in this fall, and you can wear them one of two ways: with flats and a basic tank (as seen on the supermodel) or dressed up with pumps and a colorful topper like Jess. Both were spotted in Nic + Zoe bottoms.

Matching crop tops and pencil skirts? So hot in Hollywood right now. The singer and actress both clearly got the memo, each flashing some skin in this sexy white lace Misha Collection set.

We want this Sam & Lavi jumpsuit as badly as you do. Unfortunately, it's sold out basically everywhere. So unless the reality star or supermodel want to have a clothing swap (hey, it could happen!), we're all out of luck.

How you vote on this Rails showdown may depend on how you style your own favorite chambray shirt: With a pair of skinnies (as seen on Eva) or tied at the waist with a mini (like Julianne).

NICKI VS. KIM VS. SHAILENE

Sure, crop tops may be de rigeur in Hollywood at the moment. But this one is especially noteworthy because three A-list stars have worn it – and it costs more than three grand. It's time to pick the ultimate Balmain bombshell.

This Parker mini delivers maximum impact whether on or off the carpet. We just can't decide whether we'd rather style it with flats and a cross-body (like Jessica) or with platforms and a sparkly clutch (on Michelle).

LILY VS. NICOLE

Sometimes editors show up to work in the same J Brand jeans, so it's no surprise these two singers are facing-off in this ripped pair. Slightly more surprising? That they both bared their midriffs. Lily shows a slice of stomach, while Nicole chooses to show off a bit more.

Apparently, this Elisabetta Franchi jumpsuit comes with one styling rule: Wear with nude pumps. The stars clearly got the matchy-matchy memo, but they diverged when it came to the belt selection.

Not only are the reality star and singer wearing the same Frame denim pencil skirt, but they topped it with even more denim. And not that we buy into those Kim/Bey feud rumors, but we will say that Bey wore it first.

Even red-carpet superstars need to take a day off – and they do it in the actress-off-duty uniform of a striped top (theirs is Splendid) and jeans.

NINA VS. HEIDI

Everyone has a favorite black bikini. And the actress and supermodel happen to have the same fave: a Basta Surf two-piece with neon trim.

LALA VS. CASSIE

It takes a brave star to wear a bright yellow sheer dress with crochet detailing. And both LaLa and Cassie are clearly up for the challenge in this For Love and Lemons design.

TAYLOR VS. REESE VS. ROCSI VS. JESSICA

After seeing this Monica Rose for Lovers + Friends outfit on four different stars, your reaction is probably: "I need it in my closet now." But unfortunately, this look is sold out.

JENNY VS. SHAILENE

The 41-year-old TV host brings a glam vibe to this low-cut Stella McCartney design thanks to her old Hollywood curls and massive danglers. The 22-year-old actress takes a more laid-back (and youthful) approach with a trendy serpent arm band and side-swept pixie.

KATY VS. CARA

There's one very subtle difference in how the singer and the model style their pepperoni pizza onesies.But if you're not, like, a fashion person, you might miss it so don't feel bad.

KATE VS. EMMA

Not a fan of matchy-matchy outfits? The supermodel's way of wearing her Fendi dress will probably nab your vote. But if you're all about coordinating your dress to your shoes to your lips, Emma is your girl.

JOURDAN VS. AMBER

With legs like that, Jourdan and Amber could each nab their own shaving cream campaigns, but only one can win this Stella McCartney "Greta" mini showdown.

DANIA VS. ASHLEY

The most important accessory for this Cushnie et Ochs dress: great abs, which both ladies clearly have. The Devious Maids star lets her toned stomach take center stage, while our Celeb Style Council member covers up a bit, adding some edge via a leather jacket.

BLAKE VS. TAYLOR

If you watched Blake in this video, you know she paired her color-block Roland Mouret stunner with colorful studded Louboutins. The Orange Is the New Black star, on the other hand, went for a more matchy-matchy vibe with blue Stuart Weitzman sandals.

MEL B. VS. LIZZY

One formal Roksanda skirt, two very different ways of wearing it. The X Factor judge pairs her color-block bottom with a strapless black top, while The Masters of Sex star shows less skin in a long-sleeve black-and-white shirt.

KRISTIN VS. CARA

This is one of those effortless maxi dresses that you throw on with a pair of sandals and never want to take off. Good news: It's affordable and still in stock. Bad news: You still have to make the tough choice of who wins the Faceoff!

NINA VS. ROSARIO

We'd probably wear these checkered Bionda Castana pumps with something simple; an LBD, maybe, or black pants and a white tank. But these actresses go for a more advanced look, pairing their busy shoes with equally head-turning dresses.

ERIN VS. LUPITA

There’s no doubt this ivory bow-embellished Lanvin dress looks awesome on both stars' toned bodies. So the question you need to be asking yourself is: Do I like it better with sleek nude sandals (on the TV host) or red suede pumps (on the actress)?

CIARA VS. HARRY

Calvin Klein is all about bringing the '90s back with this "Obsession" sweatshirt, and these style-setting singers are more than happy to sport the unisex design. The $895 price tag, however? We’re slightly less obsessed.

LINDSAY VS. NAOMI

True story: One editor bought this Kate Moss for Topshop dress and it was so heavy, she had to return it. But LiLo and the supermodel manage to make wearing the beaded fringe design look easy.

SELITA VS. ROCSI VS. FAITH VS. KATHARINE

We’re no longer surprised to see one star after another wearing this Haute Hippie tuxedo dress. The only thing that keeps us guessing? Whether or not they'll be wearing a bra.

LIV VS. BLAKE

This Rag & Bone onesie is part jumpsuit, part overalls, altogether awesome so it's no surprise these trendy stars both have it hanging in their closets.

PIPER VS. NAOMI VS. JENNIFER

The Covert Affairs star eschewed a white gown on her wedding day for this metallic animal-print Michael Kors stunner, which may have been her "something new," but wasn't new to us (we'd seen it on two celebs before).
