• Traditional thong: This style is generally the most common and involves a strip of fabric in varying widths on the rear of the garment connecting the front or pouch to the waistband.

• G-string: This style consists of a string of fabric - as opposed to a wider-than-thick strip - connecting the front/pouch and the waistband in the rear.
