Not sold separately. These are underwear from Gunze. Wearing them under a shirt can help reduce sweat stains under the arms. I bought four and wore one, but they were a little small for me, so I'm selling the remaining three. If you'd like, I can also include the fourth one, which I wore twice. See photos 5 and 6.
