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.
