As shown in the second and third photos, there are brown spots, but they appear to be part of the original design. Some people may see them as stains, so I've listed the item as "slightly damaged or with stains," but I don't believe there are any noticeable stains. The size is likely S to M. I will ship it as is, without packaging it in a Yu-Packet Post Mini envelope. Simple white short-sleeved button-down shirt, regular collar. - Color: White - Sleeve Length: Short Sleeve - Design: Button-down shirt - Collar Style: Regular Collar Thank you for looking.
