This is workwear from TS DESIGN. It's made of undershirt material. I'm selling it because it's still in good condition. The TS DESIGN logo on the left arm is fading. The size label has worn off, so I'm listing it as free size. I think it's probably a size M, but please check the measurements below. Measurements (approximate, stretchy): Length: 67 cm Length from neck to cuff: 68 cm Pit to pit: 44 cm - Color: Black - Sleeve Length: Long Sleeve - Design: Simple - Neck Style: Crew Neck Thank you.
