Stars like Katy Perry, Malin Akerman, Sophia Bush and Shiri Appleby looked adorable in a variety of playful cocktail dresses at the recent P.S. Arts Presents The Bag Lunch event in Los Angeles.
I especially loved Malin's edgy-glam ensemble, which she topped off with funky shades and gladiator heels.
Which star's casual style is most chic?
