Last night's What to Expect When You're Expecting premiere drew out the film's stars and style stars alike at NYC's AMC Lincoln Square Theater. There, the night was just as much about the red carpet as it was about the movie, with the film's leading ladies, Brooklyn Decker, Elizabeth Banks, and Cameron Diaz treating us to the chicest kind of Spring dressing. Brooklyn's pal Chrissy Teigen also stepped out to celebrate the movie, opting for a flirty sequin skirt topped with a crisp white blazer. Cameron Diaz played to the menswear trend in an understated white button-down and black trousers, offset with a statement chain necklace. Elizabeth Banks brought the dressiest look in a floral, beaded, and cutout Peter Pilotto sheath, while Brooklyn Decker took a more minimalist approach in a body-skimming white strapless, finished with gold accents and creamy platforms. Each showed off her own brand of seasonal event wear, now we're asking you to pick favorites — who gets your vote for best dressed at last night's premiere?
