This item was purchased at Yofuku no Aoyama. I tried it on after purchasing it, but the size didn't fit, so I am selling it. I only wore it once for the fitting. After that, I washed it and kept it in storage. - Size: LL - Material: 79% Polyester, 21% Cotton Can be worn as casual wear, for COOL BIZ, or as an inner layer for a suit.
