Elegant Rio briefs made from swimsuit fabric with subtle draping at the waist and a gemstone detail. The briefs have a smooth finish at the top so they don't cut in and the draping creates a lovely waist. The higher cut of these Rio briefs optically lengthens legs. Cocktail is the little black dress of the PrimaDonna swimwear collection. With its gossamer ruching and outstanding fit, this swimwear is always flattering and on-trend. New this summer: the trendy triangle top, a swimsuit with crossed straps, and the chic 60's-colour Booboo Blue. Booboo Blue is a warm blue-green with 60's allure.
