Rihanna and Ciara battled it out on Twitter earlier this year after CiCi bashed Rhi Rhi on E!’s Fashion Police. Can you imagine the looks they'd give each other if they showed up at the same time in this dress?

Ciara wore the Cushnie Et Ochs pre-fall 2011 design first to the New York screening of The Hangover: Part II in May. Her accessories, a gold cuff and nude Christian Louboutin heels, added a touch of glam that made the summery jersey dress more red-carpet ready.

Rihanna, on the other hand, completely dressed down the frock with Vans Lo Pro sneakers, aviators and a snap back turned sideways when she stepped out in the New York heat to party at a SoHo club.
