The negligee trend is a tricky one to pull off (how do you dress up a nightie?) but guess who went and mastered the look at a Beverly Hills party on Thursday? Only Hollywood's super stylish twenty-something, Lily Collins.
Although this red and black combo had the potential to look a little trashy, the actress kept her look chic and simple with a matching pair of court shoes, a matte lip colour and no accessories.
Her blunt crop made this statement dress look all the more effortless and those lashes? We'd like to know which mascara Lily used please.
