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.
Yep, Lily got heads turning as she arrived at Flaunt magazine's event in a slinky slip.
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.
Lily wasn't the only one to experiment with her style either. Selena Gomez made her seriously low-cut dress look chic thanks to a plum pout paired with her messy plait. Perfect.
