After Breast Surgery - Breast Prosthesis - Bras - Bodysuits - Swimwear Our bras fit snugly to the chest wall, and hold the prosthesis against the body to ensure there are no bulges under the arms and the straps do not cut into the shoulders. Bras available after mastectomy are gentle yet reliable, and they are specially designed and made to support a breast prosthesis. The bras have pockets made of soft cotton or micro fibre, wide band under bust plus adjustable straps for a high level of comfort.
