Abstract: Disclosed is a breast pump support garment. The garment secures a breast pump intake component to the breasts of a user with horizontal openings created by panels that are secured at one or both ends by bar tacks. The bar tacks resist further expansion of the opening by providing better structural support at its ends. An upper support is also provided with bar tacks extending vertically upward to provide better support and geometric positioning of the opening. An elastic band or ribbon can be sandwiched between two fabric panels around the periphery of the garment, and the panels of the garment can be a combination of single and multiple ply to provide more rigid and flexible portions.
