Queen of seductively sweet underthings, Italian designer Guia la Bruna arrives stateside in an exclusive partnership with J.Crew. So unless you're jetting off to Europe anytime soon (and in that case we're jealous), we're now the only retailer in the U.S. to carry her swimwear. To create this itsy-bitsy bikini, our designers worked with Guia to choose two extra-special prints, Mitsi and Pepper, from England's esteemed Liberty Art Fabrics (the colors are exclusive to J.Crew). With ruffled trim, a demi-cup top and low-rise elasticized bottoms, this coquettish cotton set is better suited for sunning than splashing or surfing. It runs small and fits an A/B cup best, so if you've got it (but don't necessarily want to flaunt it), size up for a bit more coverage.
