Brooklyn Decker at Wantful Benefit in LA | Pictures

Brooklyn Decker, Amy Adams, and Emma Roberts stepped out for a good cause at the Wantful: The Art of Giving benefit in LA yesterday. The event, which was hosted by Rashida Jones and benefited the International Rescue Committee, also brought out Rashida's Parks and Recreation costar Amy Poehler, as well as Kristen Bell and Ali Larter. The group, including some of their significant others, posed for photos together before sitting down to dinner.

Emma was dressed in a silky black tee and striped Vena Cava skirt for the gala, a far cry from the look we last saw her in. She paid homage to her aunt Julia at a Halloween party over the weekend by re-creating the infamous outfit from Pretty Woman. Brooklyn talked about her own Halloween costume plans on Twitter, saying that she had picked a look that is both "scary and funny."
