Abstract: A nursing bra with a replaceable cup unit and a support garment is shown and described. The support garment includes an anterior exposure section that leaves the area between the nipples substantially fully exposed when the support garment is donned without the replaceable cup unit. When the replaceable cup unit is attached to the support garment, and the nursing bra is donned by a wearer, the area between the nipples is substantially fully exposed to the cup unit. In certain examples, the breasts are substantially fully exposed to the cup unit. In certain other examples, the replaceable cup unit includes two cups comprised of a cup material and an attachment feature formed from an attachment feature fabric. The replaceable cup unit's cups are fixedly attached to a cup holder, which comprises a fabric that includes attachment features formed from an attachment feature fabric.
