Emma Stone set film wardrobe costume retro 40's 50's dress buttons rust brown heels trailer The Ganster Squad

Emma Stone looked lovely in period clothes on the set of her new pic, The Gangster Squad, in Los Angeles on Saturday.

In the film, Stone is reuniting with Crazy, Stupid, Love co-star Ryan Gosling -- they play love interests again!

At least they're past that "awkward first kiss" stage. And both are dating other actors (and co-stars) anyway -- Ryan is hooking up with The Place Beyond the Pines co-star Eva Mendes, while Emma is dating The Amazing Spider-Man leading man Andrew Garfield.
