You can barely flick through a glossy fashion mag without seeing a snap of boho-grunge extraordinaire Mary-Kate Olsen or her stylish twin, Ashley but their little Louboutins will have to step aside as there's a new kid on the block. The girls' younger sibling, Elizabeth may be three years their junior but she's certainly hot on their heels in this luscious, little black number at the New York Film Festival presentation of her new production, 'Martha Marcy May Marlene' last night. Proudly flaunting a skull-embellished McQueen clutch to complement her fabulous McQueen LBD and ebony, velvet McQueen wedges (we're not jealous at all, we promise), mini-Olsen looked quite simply divine. High necklines and decorative ruffles are big on the catwalks this season so if you want to make like Elizabeth and rock the trend in style then look to our collection of ravishing ruffles) for some inspiration. We've found Elizabeth's McQueen dress below along with our pick of the best to emulate this enviable ensemble.
