A hands free pumping bustier provides a nursing woman with a convenient way of supporting funnel-shaped breast shields that are used as the nipple and breast interface during expression of milk. The bustier features breast shield ports having additional support members that extend upward to a top band of the bustier, providing superior support for the breast shields, enabling the bustier to accommodate differently sized breast shields, and simplifying manufacture of the bustier. The bustier further features a hook at the top of the zipper, which helps the nursing woman to easily maintain the garment around her body as she uses both hands to secure and zip the zipper. The bustier is made of a stretch nylon multi-filament yarn, such that it has adequate stretch capability to accommodate women of different body sizes and shapes while maintaining comfortable compression of the breast shields against their bodies.
