Market Studios Button Up Shirt Mens Size Small Black Vision Quest Skeletons NWT

This is a Market Studios button up shirt, new with tags. It is lightweight. Has wood buttons with an extra button on the inside care tag. Designs are tropical plants, skeleton, animal. Please see photos for measurements. There is an area to the inside of the shirt that is discolored, I have no idea what it is since this is a new shirt, possibly happened during production? It didn't bleed through to the front, but there is an area on the front as well, but it is covered by the shirt. See the photo where I am pointing to it unbuttoned and then the next photo is what it looks like with the shirt buttoned, can't see it at all. Even though you can't see this flaw, the price is reflective of it.
