Last Night’s Look: Love it or Leave it?

Check out the head-turning outfits Britney Spears, Duchess Catherine and more stars were just spotted in! Then decide – fabulous or fashion fail

DUCHESS CATHERINE

The Duchess of Cambridge’s stylish tour of Southeast Asia continues in Singapore with another hit: a belted, full-skirted suit and her trusty Stuart Weitzman wedges.

BRITNEY SPEARS

Though co-judge Simon Cowell says Britney is “quite mean” on The X Factor, she looks awfully sweet in this blue sheath featuring an oversize orange paisley print at the show’s premiere in L.A.

AMY ADAMS

Maybe it’s the glam makeup, the deep-V striped dress with a leopard-print panel or the sexy Brian Atwood shoes, but we had to do a double-take before realizing this was Amy (at the N.Y.C. screening of The Master), a star who usually goes for sweet, simple and understated.

KERRY WASHINGTON

We’d love to hang out with Kerry, raid her closet and get all her skin tips – because maybe then we’d look as radiant as she does in her lace-embellished ivory dress, worn with matching accessories and Le Vian jewelry to a Beverly Hills Paley Center event for her show Scandal.

ALLISON WILLIAMS

Also at the N.Y.C. premiere of The Master, the Girls star goes for major impact with minimal styling, wearing nothing but a body-hugging red dress and nude platform sandals.

KRISTEN STEWART

Smoky eye makeup, a messy updo and an edgy outfit (an open white blouse, gray tank, black A.L.C. pants and killer Jimmy Choo heels) make the actress look like quite the bad girl at a New York screening of On the Road.

KATE MIDDLETON

She’s quite the modern princess – and she’s got a modern dress to match. Kate slips into a colorful Prabal Gurung creation, complete with a black clutch and matching pumps, while visiting Istana, Singapore, with Prince William as part of the Jubilee tour.

EMMA WATSON

Leaving her minis in the closet, Emma opts for pure romance in a beaded, pale yellow Giorgio Armani gown at the Perks of Being a Wallflower premiere in Hollywood.
