Kourtney, Khloe and Kim Kardashian, who’ve already designed a collection for Bebe together—are now taking a stab at swimwear. The sisters sat front row at Miami Swim Fashion Week to watch the debut of Kardashians for Beach Bunny swimwear. “All glammed up for the Beach Bunny in Miami with Kourtney and Khloe,” Kim wrote on her official Web site.  Their suits aren’t much different than what they favor on the red carpet: metallics, embellishment and sexy cut-outs.
