1) A particular cut of a brief or leotard (or in clothing fashioned after said articles, such as a teddy, a bodysuit,
dance belts, etc., ad nauseam) where, rather than having fabric covering the buttocks, there is a strip of fabric that lies between the buttocks. Usually done either for sexual appeal or to cut down on panty lines - or both.
2) A
popular model of sandal with a rubber sole, and two fabric straps to hold the foot in, in such a fashion that it connects near the
front of the sandal in a knot that rests between the big and second toes.
