Open Cup & Peekaboo Bras

A shelf bra supports the lower part of the bust while leaving much of the upper bust uncovered. Some designs use a partial cup, while others have a more open construction, which is why shelf bras can overlap with open cup, cupless, and peekaboo bras.

A peek-a-boo bra uses openings, cutouts, straps or partially open cups to reveal more than a traditional bra. The term can cover several constructions, from small cutout details to more open cup silhouettes.

A quarter cup bra is designed to provide lift and lower-bust support with minimal coverage. It can be worn as a statement lingerie piece or under clothing when the cut and fabric of the outfit allow for it.

Ouvert lingerie is designed with intentionally open areas or cutouts rather than full coverage. Depending on the piece, that may mean open cups, open-back details or other strategically uncovered sections.

Cupless and open cup bras can be worn as statement lingerie, layered under sheer pieces, or styled beneath clothing when the neckline and fabric work with the bra's construction. Fit still matters: the band and straps should feel secure even when the cups provide little or no coverage.
