Camisoles, in general, are great wardrobe staples because they can be worn under a garment such as a sweater, blouse, etc. for warmth, protection, and comfort. A well designed mastectomy camisole with lace trim and some spandex is wonderful to wear under a jacket for day or evening wear. Lots of women wear them on their own with jeans together with a casual sweater for evening when the weather chills off.
A mastectomy camisole provides fashion as well as great coverup with different necklines to choose from, built in bras to hold a prosethesis, and similar support as a bra. Some also serve as compression camisoles for those who develop torso lymphedema and require graduated compression rather than simply comfort spandex.
