Sienna Miller

We had a lot of beautiful looks to pore over this week, what with a fancy Vogue dinner and the 2013 Cannes Film Festival taking place, but we had to be selective and whittle our list of favourites down to 10. When it comes to the absolute best, no-holds-barred beauty looks of the week, we have to be wowed — and wowed we were when we caught sight of Cara Delevingne's Cannes look. It was dramatic, sexy and could've easily gone wrong. . . but it was so right. Jennifer Lawrence also opted for a bold lip, and speaking of bold, we were huge fans of Nicole Kidman's futuristic ponytail. On the other end of the spectrum was Zoe Saldana, looking better than ever with her face bare and hair au naturel. Click through to see who else made the cut!

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.

Strap in as we keep up with what our fashion and beauty favourites have been up to this week! Top supermodel Coco Rocha landed in Sydney ahead of the very chic Bespoke summit, held at the Sydney Opera House during the week, while overseas, Sydney girl Phoebe Tonkin hung out (and looked stunning) with Jaime King. Celebrity stylist Romy Frydman took to Singapore to style Collette Dinnigan's runway collection, Rihanna rocked some Chanel flats and Miranda Kerr shared a new snap from Vogue Italia. . . But the cutest picture of the week? It has to go to Sienna Miller, glowing with happiness with her baby daughter on her lap (Marlowe's ponytail is so cute it hurts). Click through to see it all!

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 form-fitting. All the proof you need, according to Sienna Miller, is right here.

Whether they've been around for a long time or a short one, these English beauties have, to take a term from their French neighbours, a certain je ne sais quoi that catapulted them to It Girl status the moment they hit our radars. And one quick glance at the guest list at the 2013 Met Gala proved that this British invasion isn't ending any time soon. Alexa Chung, Jourdan Dunn, Sienna Miller, Rosie Huntington-Whiteley, Cara Delevingne and Ashley Madekwe (complete with a new bob!) all put their best beauty looks forward on Tuesday — so consider this gallery an homage to some of their best hair and makeup looks ever.

The Tribeca Film Festival wrapped up on Sunday and the annual event brought plenty of stars to NYC. Kate Hudson stunned in a white Jenny Packham dress to attend the premiere of her film The Reluctant Fundamentalist, while Zac Efron linked up with Heather Graham for the debut of At Any Price. Bryce Dallas Howard and Ari Graynor got together for the Women's Filmmaker brunch, and Mira Sorvino hung out with Whoopi Goldberg. Click through now to see all the festival fun!

In honour of this week's focus on all things denim, we're looking to some of our most all-timing inspiring denim icons. Along with the LBD, a pair of well-fitting jeans is a wardrobe essential. Transeasonal, super-versatile, durable and eternally chic (when you pick the right cut), there's a reason why denim's become part of our modern uniform.  Take a gander at these iconic denim looks for some classic inspiration. Think Claudia Schiffer in her bootcuts, Cher giving hers a bohemian spin, Alexa in her double denim, Farrah in her flares and Brooke Shields and her world-famous Calvins.
