Fashion Faceoff: Jennifer vs. Kate and More!

JENNIFER VS. KATE

The faceoff gods must have orchestrated this matchup just for us. Not only does Jen want Kate's "rolled-out-of-bed" hair, the actress also takes a page from the supermodel's style playbook, stepping out in the same suede Balenciaga flared dress.

CARLY VS. SELITA

Sure, the stars are wearing the same skirt and tee combo by Tsemaye Binitie, but Carly gives the look a slightly less feminine, more rock-and-roll feel by removing the skirt's second sheer overlay.

EMMY VS. KRYSTEN

The actresses channel their inner pinup girls (and show their patriotism) with the exact same look – a navy polka-dot Stop Staring! dress, red pumps and matching red lips. But who is the queen of this retro ensemble? Good luck deciding!

ZOË VS. ALESSANDRA

When we run errands, we're usually in yoga pants and a schlubby T-shirt. But not in Hollywood! Both Zoë and Alessandra go casual (and still manage to look hella chic) in the same paisley-print Ella Moss pants. The Star Trek Into Darkness star tops her bottoms with a white tee, while the Victoria's Secret Angel adds a coordinating lavender tee and purple-and-gray scarf.

CHELSEA VS. VANESSA

These Disney alums share a mutual love for bold color and lots of sequins. Case in point, this electric yellow Alice + Olivia by Stacy Bendet dress. Chelsea tones down the shine with nude pumps, while Vanessa adds even more sparkle with gold sandals.

GABRIELLE VS. JULIANNE

Who's afraid of dangerously low necklines and fashion-forward onesies? Not these ladies. They both pair the red Bec & Bridge number with metallic sandals – and even show it off with the same stance!

ALESSANDRA VS. OLIVIA

This Lovers + Friends dress has been spotted in the StyleWatch fashion closet, and we all keep walking by it longingly. Alessandra got her hands on one (lucky) and wears it with chic flats, while Olivia opts for neutral wedges.

Fashion Faceoff: Jennifer vs. Kate and More!

RIHANNA VS. KANYE

The fact that Rihanna and Kanye are in a Fashion Faceoff isn't even the most shocking part; it's that they both style their Givenchy Rottweiler tees from the same collection strangely similarly: tucked into leather bottoms and under open jackets.

Fashion Faceoff: Jennifer vs. Kate and More!

DIANE VS. MOLLIE

From punk to pretty: Diane edges up her printed Marni mini with a black belt, moto boots and an oversize satchel. But The Saturdays singer goes girlie by adding a pop of color via neon peep-toes.

AMANDA VS. KATY

Moto jackets are practically mandatory in Hollywood, so it's no surprise Amanda and Katy have the same AllSaints one. Amanda wears hers over a girlie Saint Laurent dress, and Katy is all rocker, pairing it with a graphic tee and leather pants.

HEIDI VS. KATE

The official uniform for the Hot Blonde Moms Club must be this 291 graphic pullover, which they each love to wear with jeans.

ALLISON VS. JENNIFER

We always thought Marnie was more of a Monica, but the Girls star wears the same Christian Dior tuxedo-style bustier as the Friends alum selected, even styling it similarly with black bottoms and classic pumps.

GWEN VS. KOURTNEY

Checkmates! Gwen and Kourt are two of the few stars edgy and fashion-forward enough to pull off this Kelly Wearstler trench, which they both pair with black leggings, boots and sunnies.

ANNASOPHIA VS. KRYSTEN

Two fairy nymphs? No, it's two Hollywood stars in white, feathery, ethereal Alice + Olivia by Stacey Bendet dresses. The Carrie Diaries actress keeps the look ladylike with silver pumps, while Krysten mixes it up with black peep-toes and a laser-cut clutch.

LOUISE VS. ZENDAYA

Hollywood can be a jungle, and stars are starting to dress the part. The British fashionista and tween go tropical in Juicy Couture's Palmetto jacket and matching shorts, both adding white shoes and air ties.

KATIE VS. JESSICA

Not only do both actresses have the same Isabel Marant leather jackets, but they also are apparently both on their way to audition for a '90s rock music video. What a coincidence!

ASHLEY VS. STACY

Can you spot the subtle difference between Ashley's Rebecca Minkoff ensemble and Stacy's? Hint: One's a dress and one isn't.

LAUREN VS. MARIA

It makes sense that two of the L.A. ladies whose style we most covet are wearing a dress by a designer whose creations we covet. They're in versions of the same Kate Spade New York "Rainey" dress.

HILARY VS. KATHARINE

Hilary styles her draped Lovers + Friends skirt in a Hollywood way (bustier, layered necklaces, booties), while Katharine gives it a Coachella feel (button-up, funky sandals, shades, ombré bob).

LUCY VS. OLGA

You know what they say: If you love it, buy it in two colors. Well, if we had enough cash to get two Roland Mouret gowns, the shades we'd pick would be these, black and emerald.

SELENA VS. KATY

Here’s a sentence we never thought we'd type: Look how versatile this floral Dolce & Gabbana bustier is! The teen queen wears hers with nude heels and a pencil skirt, but Katy goes all out and adds a Dali-print mini and chunky white heels.

KATIE VS. RIHANNA

On Katie, Current/Elliott's $198 "Perfect Shirt" is a fun, casual beach coverup. On Rihanna, though, the same piece somehow becomes edgy and fashion-forward.

JAMIE VS. EMMY

ALEXA VS. CHLOË

Half of the editors here prefer this Simon Rocha number in black on Alexa with funky heels, but the rest of us like it in lemon yellow on Chloë, with her glam ankle-strap pumps. So, we need you to help break the tie.

OLIVIA VS. NICKY

Olivia gives her super-girlie Valentino dress some edge with studded heels and an equally sharp bracelet, while Nicky embraces the sweetness of the design with feminine peep-toes and milkmaid braids.

ASHLEY VS. KHLOÉ

The Twilight star wears her Antonio Berardi dress with a ladylike below-the-knee hem and classic pumps, while the youngest Kardashian sister gives hers a sexy makeover, shortening it and adding eye-catching heels.

JULIANNE VS. JULIANNE

It's a battle of the Juliannes, who both select the JET by John Eshaya leather-sleeved army jacket. They even style the topper similarly: with ombré shades and black skinnies.

MISCHA VS. VANESSA

Considering crop tops are so huge for spring, we suppose we shouldn't be so surprised that these two stars have the same darling lace Katharine Kidd ensemble.

AMANDA VS. MINDY

Two funny ladies, one interesting dress. The actresses step out the same Saint Laurent baby-doll silhouette with a dotted yoke, though the shoe choices couldn't be more different.

SARAH VS. MORENA

Who looks sweeter in this bow-accented Paule Ka dress: the Modern Family star with her loose waves and silver platforms, or the Homeland actress, in her updo and pumps?

LAUREN VS. KELLY

On Lauren, this Camilla and Marc jumpsuit is sweet and slightly preppy. On Kelly, however, it takes on a very "Ozzy tribute" vibe.

JADA VS. ADRIANA

Can you guess which star is wearing her Alberta Ferretti gown the intended way and who has it on backwards? This is a tricky one, but Jada's wearing hers correctly. (Though we have to admit Adriana's 180º rotation works too.)

EMMY VS. HILARY

This might be the last jacket faceoff you see for a while (Mother Nature willing), so be sure to really soak in the chic, military-inspired Gerard Darel peacoat Emmy and Hilary are wearing.

KATE VS. SHAY

We can either envy these two stars for getting their hands on the Derek Lam for Kohl's collection before it hits stores on April 5, or we can admire them for loving a bargain (it's only $70!) as much as we do.

MIREILLE VS. EVA

The Killing's star looks almost angelic in her slashed and sequined white Emilio Pucci gown, but in black, on Eva this number is sexy and daring.

FREIDA VS. LEA

The two brunette beauties are like a valentine to Valentino, each in their red and pink versions of the same strapless, ruffled gown.

JESSICA VS. ANNE

A lesson in wearing cozy crochet sweaters brought to you by Jessica and Anne (in the Paper Denim & Cloth "Lexington" style): Do it casually by adding colored jeans, or dress up the top by layering it over a maxi dress.

ASHLEY VS. JESSICA

Two starlets, two colors, but only one dress can win this tough-to-call Fashion Faceoff. Do you prefer Ashley's neon version of this $398 RVN number or Jessica's cool blue-and-white look?

KYLIE VS. WILLA

Both stars get fringe benefits from this yellow Stella McCartney brocade dress, but while Kylie keeps her accessories low-key, Willa opts for attention-getting ivory add-ons.

ANNASOPHIA VS. ZENDAYA

The Carrie Diaries star wears this Alice + Olivia "Lollie" dress ($795 here) on set, giving it an '80s vibe with a bright belt and jean jacket. But Disney tween Zendaya prefers a more 2013 feel, sporting it with a sweater and chunky brown sandals.

GWYNETH VS. KERRY

What looks great with a short-sleeve cream Wes Gordon sweater? According to these two stars, the answer is a flouncy mini, though the Goopster opts for a white skirt and the Scandal actress goes for black leather.

HANNAH VS. CARMEN

Both ladies have the killer curves required to wear this high-slit, strapless Rafael Cennamo gown. So, really, it comes down to whether you're on team blue or team red.

JULIANNE VS. KHLOÉ

Apparently this shocking shade isn't as hard to pull off as we thought. Two stars with different skin tones, different hair colors and different body types look pretty amazing in their neon KaufmanFranco gowns.

Two more ladies giving in to their animal instincts: SJP keeps her spotted Current/Elliot top casual with distressed boyfriend jeans, flats and slouchy outerwear, but Jessica throws hers on with black skinnies and wedge sneakers.

RIHANNA VS. NICOLE

The Tom Ford gown Rihanna selected for the Met Gala may be the most demure look she's ever picked out. But the same dress at cocktail length on Nicole is one of the more avant-garde things she's worn.

TAYLOR VS. LUCY

Taylor gives her Bella Dahl button-down a casual vibe with rust-colored skinnies and shades, while Lucy adds a hat and printed Oxfords, perfect for stylish traveling. (Psst, we're as into the brand's tops as these ladies are.)

PIPPA VS. JAYMA

We wouldn't blame Jayma if she ran out and bought this Paper London "Rayleigh" dress after seeing it on Pippa last year. But did she improve on the look by adding an air tie?

Think a crewneck sweater is a snooze? Reese (wearing her Autumn Cashmere number over a button-up and riding boots) and Jessica (who tops hers with a fuzzy vest) prove otherwise.

RUMER VS. LINDSAY

Two stars who aren't afraid to be bold. They show off their midriffs in the same teal Boulee dress, though Rumer's approach is more daytime-appropriate and Lindsay styles hers for an evening out.
