style showdown: peplum, times two

Brown hair? Check. Brown eyes? Pink lipstick? Check, check. Peplum mini-dress? Check. To the same event, even photographed together? Check. You get the idea.

Rachel Bilson and Aubrey Plaza aren't only content with sharing the screen in their new movie The To Do List; clearly they're on the same page, style-wise, too.

Reminiscent of when my friends and I used to call each other to coordinate our outfits the night before school (or on the flipside, of Regina George's strict sartorial rules in Mean Girls), the actresses showed up in similar outfits at the film's LA premiere last night.

In one corner we have Rachel Bilson in a flower embroidered blue number by Oscar de la Renta, accessorized with a Christina Louboutin clutch. In the other, we have Aubrey Plaza in a cream Calvin Klein Collection dress with Brian Atwood shoes.

Obviously we love them both, but we have to ask: whose peplum minidress is your favorite?
