This is a men's Adidas short-sleeved logo T-shirt, size XS. There are no stains or dirt, as far as I can tell, but there is a slight, faint sweat stain around the neckline. I've worn it a few times, but it's still in good condition and wearable. It is a used item, and the measurements are taken by a layman, but I've included them in the second image, so please refer to them.
