Olivia Palermo

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.

If last week was all about the red carpet (hello Met Gala madness!), then this week is all about off-duty celebrity style. Stars are ditching the big gowns and designer names for effortless, low-key looks. Snapped on the streets of New York or LA, jumping on (or off) an international flight, or just going about their day to day — these A-listers all rely on a concise edit of wardrobe staples. After some close and very serious analysis, we think we've cracked the off-duty style code. Step inside to see how they do it, shop the core items, then pepare to get papped! 

While it's all good and well to see our favourite celebrities on the red carpet looking beautiful, it's also nice to see them in their natural habitat, rocking equally natural beauty looks. We spotted Emma Stone getting lunch in New York wearing tonal lipstick, Olivia Palermo walking her dog with a high tucked ponytail and Rosie Huntington-Whiteley looking chic with a straight blow dry at LA airport. See the girls up close, now!

Yes, the Met Gala may have dominated the fashion headlines this week (did you see the gowns?). But, that doesn't mean we didn't have other stylish opportunities to serve our search for this week's best-dressed celebrities. Miranda Kerr and Sarah Jessica Parker's versions of dressing down — Miranda wore a loose Vivienne Westwood jumpsuit and Alexander Wang heels to a showing of The Great Gatsby, SJP wore a vintage floral dress — proved to be some of our favourite looks of theirs. . . There's something about stars not trying too hard that we love. Kate Bosworth made a case for flared skirts (hers by Miu Miu), and of course, we're still impressed by some of the Met Gala style winners — namely, Rooney Mara and Rosie HW. Want more? Right this way!

From natural, fresh-faced makeup looks, to braided hair and bold lips — there's no beauty look our favourite celebrities won't try. Julianne Moore and Constance Jablonski opted for bare faces, and we think they've never looked prettier! Olivia Palermo was all about the braided hair and our cover girl Poppy Delevingne reminded us of just how sexy a red lip (and not much else) can be. There's much more to see — including two stars with fresh fringes — so click through and have a squiz!

Last night's Pikolinos Gala Dinner at the UN drew out supporter Olivia Palermo and her signature eclectic glamour. Meanwhile, The Breast Cancer Research Foundation's annual Hot Pink Party supplied a lesson in evening elegance, courtesy of NY style crew Tory Burch, Kate Hudson, and Elizabeth Hurley. If you're looking for more in the way of cocktail dressing inspiration — or just a little eye candy — click through for the rest of the celebrity styling fodder straight from this season's most stylish galas (thus far).

Mark Wahlberg wore an all-black ensemble to the NYC screening of Pain & Gain at the Crosby Street Hotel last night. He was joined by rapper 50 Cent, Peter Facinelli, who had girlfriend Jaimie Alexander by his side, and New York Giants football star Victor Cruz for the movie's NYC debut. Olivia Palermo and boyfriend Johannes Huebl also joined Mark to take in his latest film. Missing from the action was his co-star Dwayne Johnson, although he and Mark linked up last week to premiere Pain & Gain in Miami.

Last night was an unexpectedly sombre occasion for Boston native Mark on the heels of the Boston Marathon bombings. Mark took to his Twitter account yesterday to wish his hometown well, saying, "Thoughts and prayers with my hometown Boston today." Mark was torn between supporting his film and expressing his worry for his family members back in Boston, and he conveyed his true feelings about the tragedy in an interview with reporters last night, explaining, "I really didn't even want to come tonight. I hadn't really heard much — I spoke to my mum, and most of my family seems to be OK. It's such a big event, there's so many people there. It's horrible man. It's [expletive] disgusting, man. I just — I'm very upset."
