A tight, soft bra that hooked in front was my best friend for the first few weeks following my mastectomy. If you have gauze or bandages over your surgery site, a mastectomy bra will help to keep it all in place. If you wish to use cotton or silicone breast forms, a mastectomy bra will have special pockets for those prosthetics. Many mastectomy bras are sold with drain pockets, and you can also find mastectomy camisoles if you prefer a longer style. Consider investing in two bras so you can switch off washing them.
