Get set for spring in a floral dress by Alexander McQueen

It's easy to see why English rose Lily James excels in dramas like Downton Abbey or War and Peace. But since her new movie Pride and Prejudice and Zombies is a twist on a classic, this pretty dress was the perfect choice for the premiere!

She has recently worn designer labels like Atea Oceanie, Jonathan Simkhai and Marchesa, but this time her dress is by Alexander McQueen. Her stylist Rebecca Corbin-Murray certainly does know her stuff!

We love the mashup of the delicate floral print and the somewhat risqué sheer material and bodice. This flawless piece is plucked from the Resort 2016 collection and it's really getting us in the mood for spring. The wild embroidered blooms at the bottom are beautiful!
