Thank you for viewing. The fabric is thin. The size is listed as M, but I'm not sure, so please refer to the last two photos. The inside of the collar is stained red. This is a used item, so please understand and consider purchasing. Please refrain from purchasing if you are sensitive to such things. Returns and exchanges are not accepted after purchase. The item will be folded small for shipping, so there may be creases upon unpacking. Please be aware of this beforehand. *Please note that there may be slight errors due to amateur measurements. If you are interested, please consider this opportunity. Thank you very much.
