Celebrity Style

Sienna Miller knows how to start (and own) a trend — boho chic, anyone? — but her latest turn toward a more feminine fit-and-flare silhouette is something she has actually loved for years. While Miller's long-sleeved, light blue Matthew Williamson box-pleat dress may be the most recent example of her penchant for the girlier style, she has also stepped out in Topshop, Valentino, and Twenty8Twelve iterations. And it's not hard to see why she loves a fit-and-flare dress — and why, if you haven't converted yet, it's a really flattering choice for most body types. By cinching the smallest part of your waist and letting the skirt flare out over the hips, it creates an illusion of a bombshell-like figure. And for those of you who aren't after a totally body-con fit, this route touches on something halfway to formfitting. All the proof you need, according to Sienna Miller, is right here.

The 66th Annual Cannes Film Festival kicked off today with the help of French actress Audrey Tautou, who looked lovely in a retro-style printed dress, and Nicole Kidman, who sparkled in her sequined sheath. As the sunny photocalls get under way in the French Riviera, we can't wait to see what chic daytime ensembles the stars will show up wearing. Until then, get a closer look at Kidman and Tautou's Cannes style here.

With Kate Middleton's baby bump finally showing, there comes a flurry of designers vying to dress her. And, according to WWD, they're more than willing to create custom maternity clothes for the expecting Duchess of Cambridge, too. Karl Lagerfeld, Nina Ricci, Vera Wang, and Donna Karan were among the designers to submit exclusive sketches, supplying a cool mix of daytime looks and more royally geared evening gowns, all tailored to highlight her bump.

To date, Middleton hasn't exactly been the poster child for wearing maternity clothes, having only worn one Topshop maternity outfit since her pregnancy was announced last year. Instead, she has opted to recycle her preexisting wardrobe with looks from Erdem, Mulberry, Armani, Max Mara, and Tara Jarmon — pieces that will remain wearable after the baby is born. Practicality aside, these designer sketches are undeniably fun. Click through to see them all, and tell us which design you like best in the comments below.

When Vogue and MAC Cosmetics host a dinner for Prabal Gurung, it's safe to assume the guest list is a pretty stylish set. That was the case at Chateau Marmont on Monday night, where the fashion crowd gathered to toast the designer clad in — what else? — a lineup of gorgeous Prabal Gurung looks. Diane Kruger made her way inside with beau Joshua Jackson, all while showing a little midriff in a solid crop top and a bold pair of printed pants. Ginnifer Goodwin hung with the designer du jour in a perfect metallic party dress, and Zoe Saldana showed her love for Prabal in a look from the Fall '13 collection.
