BacheloretteCOURTESY OF RADIUS-TWC

Bachelorette comes out tonight! The film stars Kirsten Dunst, Isla Fisher, and Lizzy Caplan as three girls who are asked to be bridesmaids for a girl (Rebel Wilson) they used to ridicule in high school. InStyle.com caught up with all the ladies at the film’s L.A. premiere last week, and they had a lot to say about how their wardrobes (created by costume designer Anna Bingemann) helped them create their characters. “To see that each girl can be fashionable but also have her own quirky style, and when you saw all three of them on screen it would feel complete,” the film’s writer-director Leslye Headland told us. “The character’s costume is their armor. It’s what they protect themselves with, especially dealing with female characters that are all about their image.” Click through the gallery below to hear all four girls talk about their characters’ styles and see the film in a theater near you starting tonight!
