KE$HA VS. ELLEN
Despite how differently the two stars style their Joe's Jeans button-downs, the singer and the actress have one big thing in common: They both look like they walked straight off the pages of an Urban Outfitters catalog.
ISLA VS. BAR
Tie-dye: Not just for summer days at the beach. The actress and the supermodel bring the print into fall via this Gypsy 05 dress.
CIARA VS. RITA
You may think wearing a printed turtleneck mini is a bold move. But these singers have a different definition of the word bold, as proven by the fact that they pair the Emilio Pucci stunner with even more over-the-top footwear.
ANGELINA VS. HAILEE
We really wish they were both wearing Hailee's Kenzo eye-print dress (seriously, could you imagine Angie in a mini like that?). But alas, it's their lace illusion Christian Louboutin booties that match.
LILY VS. KRYSTEN
That's not a plush throw blanket draped around the actresses' shoulders. It's a faux fur Minkpink topper! And as you can see, the coat works with black pants or a skirt.
DIANE VS. KATE
Regular women spend 20 bucks on pajama tops and wear them to bed. But these two are no regular women. They drop major cash on 10 Crosby Derek Lam button-downs and wear them with denim in public.
KATIE VS. LEANN
A leather bomber and jeans go together like Miley and twerking, so it makes sense that both stars (despite their very dissimilar aesthetics) pair the striped EACH x OTHER topper with denim bottoms.
ADRIENNE VS. MARISA
Very different curves, one sexy way to show them off. The two ladies flaunt what they're working with in the same sheer-striped Catherine Malandrino dress, even coordinating their hand-on-hip stances.
M.I.A. VS. SALMA
Let's face facts: Anyone would look cool in these crackled Balenciaga shades. But do you prefer them with a hooded pleather rain slicker on the rapper or a coordinating dress and bling-y earrings on the actress? Decisions, decisions.
JENNIFER VS. JENNIFER
They sing. They act. They've both been on the American Idol stage. They have the same name. And now they have one more thing in common: They both have this printed Christopher Kane mini hanging in their closets.
ALESSANDRA VS. HILARY
These are definitely mom's-night-out jeans. Because – whether paired with a cream topper or a sheer black shirt – these gray Denim of Virtue skinnies covered in spikes probably shouldn't be worn around children.
BELLA VS. BEHATI
If these two photos were in "Second Look" at the back of PEOPLE, we're pretty sure it wouldn't take most people too long to spot the difference: Bella sports her Blumarine mini with matching trousers, but the supermodel does as supermodels do and goes sans pants.
LIZZY VS. BRYCE
Double-breasted navy blazers with gold buttons: not just for sea captains. Lizzy pairs the Juicy Couture jacket not with a pipe, but rather jeans and boots. Meanwhile, Bryce keeps it nautical with a blue-and-white striped dress.
VICTORIA VS. CAREY
Shirt or no shirt? The designer wears a black blouse underneath the split-sleeve blazer from her line (which kind of looks like a cape). Carey skips the top in favor (we assume) of double-stick tape and puts her décolletage on display.
RIHANNA VS. STACY
In RiRi's world, these bold J Brand bottoms require an even bolder topper (re: her black-and-white checkered Saint Laurent moto jacket). On the safe side of the style spectrum, Stacy teams the same coated skinnies with a solid black blazer and graphic tee.
DOUTZEN VS. OLIVIA
Requirements for wearing this sheer-paneled Theyskens' Theory dress: nude shoes, minimal jewels, loose waves and a bod that would stop traffic. Doutzen and Olivia clearly nail all four.
JAMIE VS. OLIVIA
If these ladies were competing in a "Best Glow" competition, we'd be totally stuck, because they both look radiant in this printed Parker mini. Jamie wears hers with ankle-strap sandals and side-swept curls, while Olivia goes for platform pumps and a pony.
SARAH VS. JORDIN
Who's the princess of this Alice + Olivia peplum dress: the Modern Family star in the navy version with black peep-toes, or the singer in the red version with matching pumps?
OLIVIA VS. ASHLEY
Tied or untied? Desert boots or sandals? These are the very important questions you should be asking yourself before deciding between the two actresses in this printed Ella Moss maxi.
ROSIE VS. ALYSSA
We could say that making the call on this Faceoff is all about choosing which shoes (gold python or yellow) and hairstyle (beachy waves or pompadour) go best with this Stella McCartney jumpsuit, but let's be honest: It really comes down to how much skin you prefer to see under those cutouts.
CHLOË VS. JESSICA
Apparently both actresses believe their Westward Leaning "Color Revolution" sunnies with neon-green lenses provide all the color their outfits need since they both pair them with otherwise monochromatic looks.
ALESSANDRA VS. KOURTNEY
For many moms, a casual outfit means jeans and a tee. For these Hollywood moms, it equals this floral Ella Moss romper. The supermodel goes easy on the add-ons, heavy on the skin-baring, while the reality star adds a floppy hat and hot-pink cardi.
FREIDA VS. JESSICA
Same top. Totally different bottoms. Freida pairs her colorful Zadig & Voltaire shirt with yellow skinnies, while Jessica goes for green cargo pants (not jeans, Jess?!). What the actresses both seem to agree on: neutral sandals.
KRISTEN VS. EMILY
Looks like there is only one way to wear these gray James Jeans skinnies: with a white top, Cons and hipster shades. It's what all the cool kids are doing (a.k.a. Kristen and Emily).
HAYDEN VS. NICKI
We would have preferred a sing-off between the Nashville star and the rapper. But we'll happily take a style-off featuring their printed second-skin Alexander McQueen minis and red pointy-toe shoes.
RITA VS. NICOLE
We're not surprised that these style risk-takers selected the same cleavage-baring Emilio Pucci jumpsuit. But the fact that they both paired it with velvet accessories (a navy baseball cap for Rita and Nicole in blue Louboutin pumps) is something no one could have predicted.
HEIDI VS. ROSIE
Did Michael Kors make this dress just for supermodels? Because it looks like one must meet catwalk guidelines (tall frame, willowy limbs, great hair) to rock it. Heidi wears hers with a feather belt and black strappy sandals, while Rosie chooses a simpler waist-cincher and white pumps.
LILY VS. JULIANNE
This Halston Heritage maxi can be served up two ways: with a six-pack on the side (those would be Lily's abs) or with an orange twist, as seen on Julianne. It all depends on your palate.
CHRISTINA VS. MARIAH
First come the matching outfits – flirty pink Alaïa minis and major heels – then comes the album of duets and subsequent world tour. That's how it works, right? Yes? Please?
ROSIE VS. EMMA
After seeing the model wear her paisley-print Isabel Marant dress with heels, we're convinced it could be runway-ready. Upon seeing the actress wear it with high-tops, it looks like basketball attire. And considering how much the design costs (think: nearly four figures), you'd have to wear it in both those scenarios, plus many more, to make the cost-per-wear justifiable.
ALESSANDRA VS. SARAH JESSICA
Distressed: The word we'd use to describe the 7 for All Mankind jeans the model and the actress both have on. Also the word we'd use to describe how we feel about the socks-and-clog-sandals situation on SJP's feet.
NAOMIE VS. OLIVIA
The British actress unleashes the style power of this leather J Brand jacket with a printed dress and Jimmy Choo booties, while Olivia brings it back to its rock 'n' roll roots with a tee, skinny jeans and biker boots.
LADY GAGA VS. ELIZABETH
The singer looks like a resident of the Hunger Games's Capitol in this cutout Alexander McQueen number, thanks to full-length gloves, face paint and platform booties. Back on Earth, the actress adds regular old makeup and more traditional accessories.
ANNE VS. ROSARIO
The finishing touches on the stars' Bottega Veneta midis aren't all that varied, which is why this Faceoff all comes down to fit. That, and how unzipped you prefer the "neck fly" on the dress.
VICTORIA VS. JAMIE
Now that we know how cute this chain-embellished Princess Vera Wang for Kohl's top looks with skinnies and a miniskirt, we're probably going to nab one for ourselves. And for 30 bucks, you should do the same right after you vote.
TIKA VS. NICOLE
Some things are black and white: like this striped Stella McCartney dress. Other things are not so black and white: like who looks chicer in the two-tone mini, the actress or the fashionista.
KARINA VS. DUCHESS CATHERINE
The list of things that a Dancing with the Stars competitor and Kate have in common isn't long. It includes: owns a printed purple Prabal Gurung dress. Period. End of list.
NINA VS. MALIN
The last time two stars went head-to-head in a bright red jumpsuit (Christina vs. Jennifer), there was a clear winner. But will there be such an obvious frontrunner in this battle of the Max Mara onesies?
LUCY VS. AMY
Once you recover from the décolletage-induced trance you're currently in, vote on whether this J. Mendel cutout dress looks better in the dark monochromatic look Lucy goes for, or white with black accessories as Amy selects.
BELLA VS. JADA
Colorful shoes. Loose waves. Similar poses. We wonder if Bella taped a photo of Jada to her mirror while getting ready. The main difference is that, although they each add bold kicks to their feminine Blumarine minis, the young star slips into mint pumps and the Hollywood veteran opts for red-and-pink cage sandals.
KAROLINA VS. ELIZABETH
Hot or iced coffee isn't the only thing these stars differ on. They wear their stripes uniquely too. The supermodel pairs her Splendid tee with floral skinnies, but the actress plays it a bit safer, balancing her shirt with a solid white skirt.
VANESSA VS. KAROLINA
On the one hand, if you're going to wear an emerald sequin DVF gown with a hood, aren't you sort of obligated to wear the hood up? On the other hand, is it weird to wear a hood up at a red carpet event?
CAT VS. ALI
To pull off this bathing-suit inspired Etro dress, it appears one requires the following a.) blonde hair, b.) a very toned body, and c.) serious style cojones. (And you probably want sunscreen if you're gonna wear it outside – those tan lines!)
