MILEY IN ASHISH
There are a lot of things we'd say if we saw this sparkly distressed jean jacket and matching gold-dipped pants come down the runway. Among them would not be: "It's perfect, but replace the shirt with a denim bikini top," which seems to have been Cyrus's reaction to the look.
BEYONCÉ IN ROBERTO CAVALLI
Perhaps Bey felt this black lace gown wasn't quite revealing enough, because she lost the fur half-shrug seen in the photo at left, which obscures some of the sheer panels on one side.
CATE IN GIVENCHY
As soon as we saw this sparkly plunger hit the Paris runway, we envisioned Blanchett in it. We also correctly predicted she'd forgo the face mask, but we don't feel as much like psychics for calling that one.
BRUNO IN SAINT LAURENT
While the model shows how a rocker might style the gold blazer (leather skinnies, pointy-toe boots, open red button-down), Mars offers up the pop star way of wearing it: with a skinny tie, looser pants and shiny black shoes. The singer also beats the model in hair elevation (just barely).
KATY IN VALENTINO HAUTE COUTURE
Same tune, different tulle. Perry adds a few layers of fabric in the bust area to make the music-themed gown a bit less sheer (though she leaves the revealing skirt as is).
JENNIFER IN DIOR HAUTE COUTURE
We can't quite put our finger on what Lawrence changed about this look. Oh, wait, we think we've got it: She ditched the pearls at the collar. What a difference!
KATY IN OSCAR DE LA RENTA
Perry didn't just get rid of all that extra polka-dot tulle, which the model wears as a veil; she seems to have used the fabric to line the skirt, converting it from sheer to opaque.
RIHANNA IN JEAN PAUL GAULTIER
Ever put on a see-through skirt, beaded cone bra and sheer off-the-shoulder top then worry to yourself, Will people mistake me for a librarian? Ditching the long-sleeve part of the outfit, as the singer did, should put those concerns to rest.
JARED IN SAINT LAURENT
Reminder: We're not asking you to vote on whose hair is better (duh, it's Leto, it's always Leto). We want you to decide if the look is more fashionable with a Jordan Catalano flannel around the waist and black combat boots or as it was originally styled for the show.
KERRY IN BROOD
At first glance, these seem like two different dresses. But no, it's the same drop-waist frock. Washington gives hers a unique vibe (less baby doll, more bombshell) by removing the sleeves and bow collar.
RIHANNA IN RAF SIMONS
We have a number of firsts here: first time there's an ensemble from a men's show in Runway vs. Red Carpet. First time there's a diver motif on the article of clothing in question. And first time mesh bike shorts were added to change up the look. (Not the first time, however, that the model and the celeb have the same haircut.)
ANNA IN EMPORIO ARMANI
Faris is brave enough to wear a shiny futuristic shorts suit, but apparently not brave enough to wear a shiny futuristic shorts suit with a purple metallic bow belt as originally seen at the show.
JULIA IN DOLCE & GABBANA
The medieval cross pendant and earrings and those red-and-gold shoes certainly catch our attention. But then again, do you really need to do anything extra to get people's attention when you're Julia Roberts in a bright-red mini?
KEIRA IN VALENTINO
Some stars might see a model in a sheer design and say, "I'll take it, but add a lining." Knightley is not one of those stars. She maintains the lingerie-revealing look of the black-and-gold gown, though opts to make it every so slightly less see-through.
DAKOTA IN VERSACE ATELIER
While the catwalker bares belly button, Fanning wears the top of the crystal-covered ensemble a bit lower and the bottom a bit higher for a look that's a bit more demure. (That's right, we just used the word demure on a bustier.)
CATE IN ARMANI PRIVÉ
You've probably noticed the most obvious change to the look (Blanchett removed that feather urchin at the neck), but look closely and you'll see that she also subtly transformed the open-coat-like silhouette into a slit-free dress.
LADY GAGA IN VIVIENNE WESTWOOD
Sure, she ditched the green shadow, zombie-esque complexion, pointy talons and red pumps, but Gaga still manages to one-up the model by ditching the blouse and adding a feather-embellished top hat and seashells dangling from her hair.
HAYDEN IN GIORGIO ARMANI
There's a fine line between fashiony and costumey. For Panettiere, that line falls somewhere between bow-embellished tops and fingerless leather gloves worn with sequined caps.
MAGGIE IN DRIES VAN NOTEN
An LBD with pants? That was the designer's vision when he sent this look down the runway, but Gyllenhaal's vision varied just slightly. She skips the billowy bottoms and lets her legs (and all those feathers) take center stage.
AMY IN CH CAROLINA HERRERA
Adams loses one thing (the brooch), adds another (a bra) and makes one subtle swap (a peplum skirt, also by the designer, instead of a similar silhouette with plumes) and proves that going from runway to cubicle is possible.
CARLY RAE IN DIDIT HEDIPRASETYO
Another star who ditched the headpiece and long gloves, but kept the rest of the dramatic outfit intact, Jepsen goes all-out in this architectural purple mini.
ZHANG IN CHLOÉ
Who loves mixing and matching as much as we do? Ziyi! The actress tops the tiered skirt with a sheer button-down, combining two very different looks from the French label's show to make one that's all her own.
RITA IN EMANUEL UNGARO
Leave it to the fashion-forward singer to wear a daring gold-embellished dress just as the model does. Ora's only tweaks: rolling up her sleeves to show even more skin and ditching the leather boots for sexy black pumps.
HEIDI IN TALBOT RUNHOF
Anything she can do, I can do shorter. That's what we imagine Klum was thinking when she saw this glittery long-sleeve gown come out. In addition to significantly hiking up the hem, she also threw on a belt and removed the intricate collar.
DIANNA IN DEREK LAM
Could it be? A star who doesn't want to wear a crop top? Agron leaves the abs-flashing to the model and works a more covered-up version of the two-piece.
VANESSA IN NAEEM KHAN
When the gown is as dramatic as this beaded and feathered one, there's no need to change much to make an impact. But Hudgens adds just one finishing touch to make the dress all her own: a high slit.
DITA IN JENNY PACKHAM
This pretty white design was originally sent down the runway as a wedding gown, but Von Teese opts for it in gray and swaps the bejeweled belt for a red one to make it even less bridal-y.
BETH IN NAEEM KHAN
The catwalker gives the dress a throw-it-on-and-go vibe, thanks to her slicked-back hair and flat sandals, while Behrs ups the glam factor with polished waves, heels and a red clutch.
JESSICA IN CHANEL
Chastain is a major fan of the iconic fashion house, but we're glad she had the sense to ditch the feathered headpiece and loose lace tights (and invest in some Static Guard).
JENNIFER IN LANVIN
It's not often you see the celeb less covered up than the runway model, but Lawrence out-cleavages her competition, also forgoing the bow and adding sexier shoes.
MARION IN DIOR HAUTE COUTURE
Sure, the two have very different dos and dissimilar shoes, but we're way more focused on something else: the variation in length. The original creation was designed to hit at the ankle, as seen on the model, but Cotillard's grazes the red carpet.
ROONEY IN VALENTINO
"Oooh! Me, me, me!" That's what we imagine Mara saying when this dark, dramatic, emo-ish handkerchief dress came down the catwalk. The look is so her, in fact, that she styled it similarly, right down to the basic black pointy-toe pumps and absence of jewelry.
JESSICA IN OSCAR DE LA RENTA
The actress also chose to accessorize with an orange clutch, but that's where the similarities end. For one, Jessica's purse was a fuzzy Roger Vivier one, but she also put her own spin on the Creamsicle-colored creation at the Golden Globes with to-die-for waves and $5.8 million of bling.
JENNIFER IN ANTONIO BERARDI
When originally shown at the brand's presentation, the embroidered sheath hit above-the-knee and featured a cream belt and funky orange shoes, but at the Directors Guild of America Awards, Jennifer extended the hemline and lost the waist cincher in favor of a metallic box clutch and peep-toes.
MARION IN ZUHAIR MURAD
From a Lebanese designer's runway in Paris to a Parisian actress's closet in Hollywood: This full-skirted floral dress looks whimsical with half-up hair and ankle-strap heels, but edgy at the Critics' Choice Awards with a sleek do and nude sandals.
HELEN IN ROMONA KEVEZA
Is it just us or do the model and Helen Hunt have incredibly similar svelte figures? The only difference is that the Oscar nominee hits the SAG Awards with her hair down and adds a clutch, choker, bangles ... and a smile.
CATE IN ARMANI PRIVÉ
The catwalker in this red sequin gown may boast two dramatic black tassels and a wrapped sky-high pony, but Cate brings something else to the table at the AACTA Awards: va-va-voom cleavage.
NINA IN ZUHAIR MURAD
Another floral creation by Murad that Hollywood just couldn't resist. The Vampire Diaries actress ditched the mirrored belt and gold wedges, though, and wore her lace-and-silk mini with silver stilettos and an icy clutch at the NFL Honors event.
