This sexy Muscleskins thong is made from a heavy weight blend of smooth, stretchy, sheer pale pink lycra and nylon fabric. This brand runs small. The tag says large, but it fits like a fitted US sized medium. Please keep this under consideration. It features a very low rise, contoured pouch that has a center seam or maximum support and definition. The thong back is a traditional thong cut; however it sits lower on the waist than a traditional thong. The sides of the suit are narrow and sit low on the hip before plunging down in front to create a flattering "v" taper. Unlined and no drawstring. This suit is not for the timid. It will turn heads. The fabric is transparent and leaves nothing to the imagination. It is probably best to wear only at nude beaches and private pools. It would also be fantastic worn as underwear. It's in excellent condition and has never been to the beach or poolside.
