DIANE KRUGER

No, Diane didn't earn a bunch of Girl Scout badges for selling cookies and doing good deeds; that's just the design of her multicolored embroidered Mary Katrantzou mini, which she accessorizes with a mustard Charlotte Olympia "Pandora" clutch and a funky braid at the West Hollywood premiere of The Bridge.

KRISTEN STEWART

Even as we write this caption, we're pretty confident we know how you all are going to vote on Kristen's crop top, undies, sheer fishnet harem pants, white pumps and looped silver necklace (plus that fiery new crop) at the Chanel show during Paris Haute Couture Fashion Week.

JENNIFER LOPEZ

When you're J.Lo, you get to wear Atelier Versace ensembles before they appear on the runway. When you're J.Lo, you can also get away with wearing ensembles made up of one beaded pant leg, half a gown and major silver sandals (also Versace) to the brand's show in Paris.

KEIRA KNIGHTLEY

When this Simone Rocha midi was shown on the runway, it had a totally sheer skirt, but Keira plays it safer by adding a lining on the ladylike floral-embroidered design, accessorized with gold Prada Mary-Janes at the Begin Again photo call in London.

NINA DOBREV

The actress may be at a fashion show in Paris, but there's something military-esque about her Versace mini, which features epaulettes (with fringe!), gold buttons down the front, a mock turtleneck and a paisley print in red, white and navy.

PARIS HILTON

The socialite takes a fashion risk (and risks some seriously bad tan lines) with the intricately cutout sparkly white number that, despite being long-sleeve, high-neck and floor-length, manages to show off her cleavage, her legs and her abs at the BET Awards in L.A.

CHLOË GRACE MORETZ

At the Saturn Awards in Burbank, Calif., the actress's hairstyle feels subtly on-theme. She wears a crown braid that circles her head and wraps around a messy low bun (inspired by the planet's rings perhaps?).

ARIZONA MUSE

Nude: That's how we'd describe the color of the model's draped one-shoulder Emilio Pucci gown. And as soon as she turns around to reveal the open back (featuring two golden chains) of her look at the Serpentine Gallery Summer Party in London, we feel compelled to use the word again.

It's no surprise that the stylish actress gives us another very high-fashion look to vote on, choosing a black-and-white spotted crop top and coordinating pencil skirt (both Roland Mouret), plus, yellow pumps and a striped clutch at a panel event for her show The Bridge in Beverly Hills.

Is it strange that we think the most noteworthy part of this outfit isn't the bra-baring mint lace crop top or the lavender hair, but rather the extremely wide-leg pleated white pants Nicole wears to Licensing Expo in Vegas?

It may look like a crop top and skirt, but the actress's look is actually a dress. She wears the summery white-and-blue Vionnet design featuring a lotus flower print, plus strappy Casadei sandals to the One for the Boys Fashion Ball in London.

The actress told PEOPLE that this pea-green cutout J.Mendel gown featuring a sheer panel at the d├ęcolletage with starburst embellishments was on her Pinterest board "for some time" before she chose it for the awards. Oh, and that crimped updo? It was inspired by her recent vacation to Jamaica.

KERI RUSSELL

Without that pale-green sash draped across her body and tied at the waist, Keri's black-and-white gown might get filed under "pretty, but basic." The unexpected touch, though, makes the Rosie Assoulin creation really eye-catching, especially to Keri, who said the design "feels chic but real."
