Also known as: トップレスブラ
A Bra that provides at best minimal support under the Breasts, leaving the upper part and Nipples exposed. As the name suggests, it is essentially a "shelf" to hold up the breasts.
The term "shelf bra" may also refer to "built-in bras" included in some garments, such as Tank Tops and Swimsuits. This tag is only for actual bras, not for the breast support built into garments.
Not to be confused with a regular bra that has been pulled down.
