I received these from a friend, but I haven't used them because I have a daughter. This is a set of 3 pieces: 2 Uniqlo undershirts and 1 no-brand undershirt! I don't see any noticeable stains, but the two Uniqlo shirts show some wear around the neck. *See photo 5* Size is 90cm. These are long-sleeved romper undershirts with buttons at the crotch. I'm offering these to anyone who needs them.
