Fantastic new string bikini with absolutely no panty line. The brief has string sides and is hipster in design. The flat wonder edge back has fine silicone grip that prevents the brief from moving once on. It is hypoallergically tested so will not irritate. Personally I have tried them and found them to be the best no panty line brief I have ever worn. Made from very soft nylon/spandex fabric with cotton gusset. You simply have to try them.
