A “top” is any article of clothing that covers the breasts, and hangs down no lower in the front than the top of the pubic bone (an inch or two above the vulva) and no lower in the back than the tail bone (coccyx). Tops include Bras, Shirts, short jackets and sweaters, and the like. A girl is permitted to wear at most one top, which means she may not wear a bra under her shirt, for example.

The “crop top”, above, is a popular style. It is a short shirt that hangs no lower than the belly button.
