Thong

A Thong is a very revealing bottom part of a bikini, yet it is a very popular piece of swimwear. Also known as a "tanga," It generally consists of a very thin strip of material along the center of the garment's back designed to sit between the buttocks, and directly connected to the bottom front of the garment and to both sides of the front at the top via a waistband. Thongs are worn by many women who wish to keep their panty line invisible through shorts or pants. Panties are generally considered a little more "conservative" than thongs, and are essentially the basic term for lower female undergarments. Panties can be made of many materials and can be considered as sexy lingerie.
