Thank you for viewing! This is a long-sleeved romper-style undershirt for Disney babies. It's a set of two. It's thick, so it can be used during this time of year. It also has a collar, so it's cute for layering. It has been used, but I think it can still be used. The size is listed as 86cm (see photo 6). I would be happy if you could use it! Thank you very much.
