thong bikini

A bikini with a thong bottom piece. In order to be tagged as such, it must be apparent to the viewer that the female character is wearing one, especially when viewed from behind or through a reflection; the bikini, unless it is too skimpy, looks like an ordinary high-leg bikini when viewed from the front.

Most micro bikinis are also thong bikinis due to their skimpiness.
