It's a bit thick and stretchy. You can wear it under a jacket or suit! The white parts in the photos are not stains. I will remove them as much as possible with a lint roller and send it in a state without threads, but please understand that due to the nature of the color, some may still be visible. I'm selling it with a heavy heart because it no longer fits. Color: Black系 (Black-based) Pattern/Design: Solid
