I have kept this item stored at home since I purchased it. The color is black. Size M. Made of 100% cotton, so it should be suitable for those who are sensitive to synthetic fibers. 3/4 sleeves (long sleeves) Since the item is unopened, I cannot spread it out to see the inside, but from what I can see from the outside, I think the condition is clean with no noticeable stains or damage. *I would like to check for any tears, stains, or moth-eaten areas on the inside that are not visible from the outside before shipping, so I will need to take the item out of the bag to check its condition before shipping. Please understand. *Although it is a new item, it has been stored in a general household, so please understand that it is not a perfect new item before purchasing.
