Heidi Klein - Heidi Klein's powder-blue Hvar bikini top is the definition of understated glamour. It's cut from a quick-drying ribbed stretch-fabric that offers SPF 50+ protection, and shaped with underwired full cups that are held in place by self-fastening halterneck and back ties. The silver-tone metal U-shaped bar at the front is the defining feature. Wear it with the coordinating briefs for a polished vacation look.
