Thank you for viewing. This is a sleeveless top from Petit main, size 100 and 110. It has a button in the back. It also has a lining, so it's not very see-through. It can be worn not only in midsummer, but also in spring and early summer, and early autumn by layering a thin long-sleeved T-shirt or T-shirt underneath. I'm selling it because my child has outgrown it. I think there are no noticeable stains, but please refrain from purchasing if you are nervous as it has been used by a child. I apologize if I missed anything. I am also selling matching clothes. There is a possibility of changing between Yu-Yu and Raku-Raku shipping. Petit main Top Matching sisters Matching girls
