Prabal Gurung

There were two designers whose names were all over the best-dressed lists this week: Christian Dior and Prabal Gurung. Their incredible designs were seen on the likes of Nicole Kidman, Diane Kruger, Jennifer Lawrence and more this week, and we've gotta say, we're seeing some of their best work ever. Diane Kruger might be the only star who can pull off a belly-button-exposing top at a high-class Vogue dinner (and pull it off she did), and we were thrilled to see Jennifer Lawrence opt for something different after a sea of black during the awards season a few months ago. Olivia Palermo showed prints who's boss, Nicole Kidman earned her mega-star status, and Sienna Miller? Well, let's just say we're glad she's back on the scene.

When US 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 last night in LA, where the fashion crowd gathered to toast the designer clad in — what else? — a line-up 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.

Diane Kruger, Zoe Saldana and more starlets hit the Chateau Marmont in LA last night for a special dinner party held in honour of designer Prabal Gurung. Along with US Vogue magazine and MAC Cosmetics, Prabal invited a group of famous friends to celebrate his designs. Diane Kruger bared her stomach alongside boyfriend Joshua Jackson, while Ginnifer Goodwin had her boyfriend, Josh Dallas, and their Once Upon a Time co-star Jennifer Morrison for company. Prabal circulated around the event with the "wonderful as ever" Hailee Steinfeld and Star Trek Into Darkness co-stars Alice Eve and Zachary Quinto. Zoe Saldana made a stylist appearance alongside Amber Valletta and Jaime King. Rachel Zoe, meanwhile, brought husband Rodger Berman and later tweeted that they had "such a special evening!"

Yesterday Mac Cosmetics and Vogue teamed up to celebrate designer Prabal Gurung, which means the guest list was filled with stylish celebrities. From beachy waves to bright lip hues, the ladies wore a mix of casual and classic beauty looks. Click through to see the best looks.

Emma Watson picked a cut-out dress designed by Prabal Gurung for today's big Met Gala in NYC. Emma pulled back her hair to let the dress — and her toned figure — get all the attention. The theme of the night was Punk: Chaos to Couture, and as expected, there was lots of black and peeks of skin on the red carpet. For an extra pop of punk, Emma rocked only one long earring. Emma is kicking off a very exciting May — she'll be bringing The Bling Ring to the Cannes Film Festival.

This week we're awash in celebrity style, thanks to the slew of A-list parties, screenings and pre-Met Gala parties happening north of the equator. Baz Luhrmann and his Gatsby cast hosted a preview screening in NYC today, drawing a well-dressed guest list of stars and designers. Vera Wang, Prabal Gurung and Nanette Lepore represented the fashion pack, Kylie Minogue and Rachael flew the Aussie flag — both in printed two-pieces — and leading ladies Carey Mulligan (who also opted for some slick suiting) and Emma Roberts rounded out the Hollywood pack. Step inside to see who wore what. 

Mad Men's cast of leading ladies hit their season six premiere in LA — and safely covered a number of new season dress trends with their respective event looks. It's not the stuff you'll see Betty, Peggy, or Megan sporting on screen. January Jones brought a colour-blocked pastel blue Jonathan Suanders Spring '13 dress and metallic Louboutin heels to the red carpet. Elisabeth Moss sported a peplum-trimmed LBD by McQ Alexander McQueen — and a Lucite Charlotte Olympia clutch in hand — and Jessica Paré brought a gorgeous wash of colour and print on a Prabal Gurung sheath dress.
