Size D adjustable bralette bikini top by Bingo Surf, brand new with tags. Bralette style with tie closure in back that makes it very adjustable. Straps are also adjustable. It is D sized and in my opinion fits like a size S/M with room to accommodate a larger bust size. The color is a darker blue but not quite as dark as navy blue. Brand new with tags. Comes from a pet-free, smoke-free home.
