Sienna Miler is one of those people who makes even the most simple of ensembles look a million dollars. And the Hollywood starlet recently stepped out in style in a fitted Burberry midi-length black dress for the premiere of her new movie Just Like A Woman, that looked just that. Keeping accessories to a minimum and opting for a complementary pair of black suede pointed heels, the A-list actress was the epitome of timeless elegance. With the recent surge of attention on midi dresses this summer, Sienna's choice comes as no surprise, especially given her status as a fully-fledged fashionista.

Midi dresses and skirts were the hemline of choice for many designers this season, featuring heavily on the SS13 catwalks, from Marc Jacobs to Louis Vuitton. Not only are midi dresses the hottest hemline for summer, with a range of styles and shapes to choose from it's never been easier to dress to suit your body shape. Tight, fitted designs are perfectly suited to slim figures, whereas more flowing, loose designs will work best with curvier silhouettes.
