Abstract: A device for protecting a brassiere in a washing machine includes a pair of hemispherically shaped shells (preferably injection molded polypropylene material) adapted to assemble together over a cup of the brassiere as a protective covering for the cup. The outer shell has a circularly shaped first rim portion and a hemispherically shaped first dome portion larger than the cup of the brassiere that extends to the first rim portion. The inner shell has a circularly shaped second rim portion and a hemispherically shaped second dome portion that extends to the second rim portion, said second dome portion having a size adapted to fit within the first dome portion of the outer shell with the first and second rim portions in concentric relationship and the cup of the brassiere disposed intermediate the first and second dome portions.
