This is a T-shirt from Tomohito Shiigi, the vocalist of My Hair is Bad, as part of his solo activities. It's a size L. I bought it at a live venue several years ago. I wore it only once and have kept it in storage. When I washed it, some kind of laundry detergent seems to have gotten on it, causing some discoloration on the lower right front hem.
