Abstract: Described herein is a breast support garment and methods of use thereof. The garment can be used by a wearer with a small band size and a fuller bust and may be worn during leisure or sleep. The garment contains a sleep stay attached to an inside surface of the front section of the garment (e.g., within each cup) that can be stretched to enwrap the inner curve of a wearer's breast, thereby providing stabilization, physical separation, and/or vertical and/or horizontal support for the wearer's breast (e.g., to counter the pull of gravity on the breasts when a wearer is reclining or sleeping, e.g., side-sleeping, and/or to reduce the movement of the breasts when a wearer is changing positions or carrying out daily activities (e.g., walking)).
