Taylor Swift Elle Style Awards - P 2015

So long to girlie A-line frocks and high-waisted shorts — for now, at least.

The Dress: An emerald green Julien Macdonald gown with black lace and zipper detailing, pulled straight off the fall 2015 runway (the show only happened three days ago!).

The Wearer: Taylor Swift

The Event: At the Elle Style Awards in London on Tuesday. Swift was joined by Diane Kruger, Maggie Gyllenhaal and Olivia Wilde at the event.

Why We Dig: The "Style" crooner made an impact in this lingerie-inspired look, complete with a sexy silhouette, embellished lace detailing and heavy eye makeup. Though the 25-year-old singer typically favors sweeter looks, a la Oscar de la Renta, Swift is no stranger to Macdonald's designs, having rocked a sheer and embellished black gown by the designer at last year's Vanity Fair Oscar Party and a sparkling gold mini at the 2013 American Music Awards, both of which had everyone talking the next day. This latest look is bound to cause commotion too. Even the star's styling was more vampy than usual, with side-slicked hair, winged eye makeup and dark nail polish adding a more sexy, grown-up look than we have come to expect from Swift. Va va voom!
