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.

SELENA IN REEM ACRA

Looks like Gomez took our style prescription. And she was savvy enough not to change a thing on this straight-from-the-runway look (not even those red lace leggings).

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).

ADELE IN VALENTINO

Some stars chop their hair before awards shows, others chop their dresses instead. Take the singer, who converted the printed floral gown into a knee-length dress for the Grammys.

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.

JENNIFER IN CHRISTIAN DIOR

Less than a week before Jennifer Lawrence picked up her SAG award in this strapless navy number, a slightly modified version (no train, extra ruching) of the haute couture gown was spotted at Paris Fashion Week.

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.
