I've soaked and washed these before listing, so you should be able to wear them as is. However, if you're concerned, please wash them at home. Size is 165, set of two. They've been worn quite a bit, so there's some wear and tear. I have the impression that this type, with a double-layered chest and not a large cup size, is hard to find, and I remember it was difficult to find. Would anyone looking for this like to have them? - Color: White - Brand: twinn dimple - Type: Tank top Thank you for looking.
