Olivia Wilde impressed us again in the style stakes at the UK premiere of Cowboys and Aliens in a long black polka-dot maxi with sheer sleeves and contrasting over-sized bow. The eye-catching dress is straight from Gucci's Autumn/Winter 2011 runway (the collection is inspired by ultra-stylish Florence Welch!) and we love how it combines sophisticated elegance with a cool edge. Polka dots are huge right now and add character to a fail-safe LBD, but are subtle enough to let you mix and match with bright lips and tips. The longer length of Olivia's dress is in keeping with the quirky-glam trend we've seen trickling down from the catwalk recently and the demure collar allows her to have fun with see-through panels and a risqué split, bringing the look up to date and showcasing a fantastic pair of heels. Follow in Olivia's glamorous footsteps by mixing longer pieces with statement prints and black with white, or revealing a little flesh with sheer fabrics. This look that is begging to be worn to a chic dinner out or your next film premiere! Check out LBD's latest maxi dresses and polka-dot styles.....
