This mastectomy bra is perfect for after you've recovered from surgery and can lift you arms. There are large openings for holding prosthetics. It is made of a nylon spandex blend and is so soft, stretchy and seamless you will still want to wear if after your recovery. The padding is removable and a breast prosthetic can but put in its place. See size chart below or go with your normal shirt size. Size up if between sizes. Keep in mind that your cup size will not be the same after surgery. This bra is so stretchy it will stretch to most cup sizes, but fits best for A-D. 75% Nylon/25% Spandex Mastectomy Bra Shirt Size US S 0-2 M 4-6 L 8-10 XL 12-14 XXL 16-18 3XL 20-22
