Katy Perry spent cocktail hour with Carey Mulligan and Florence Welch last night as they helped celebrate an exhibition of costumes designed by Miuccia Prada and costume designer Catherine Matin for The Great Gatsby.
Showing her support by dipping into Prada's spring/summer 2013 collection, Katy looked pretty in wine-coloured floral prints.
Accessorised head-to-toe in the Italian label, her long raven locks were swept over one shoulder and styled into ultra-glossy waves.
Katy is on a serious style high at the moment, but are you taken with her Prada prints?
