The size is labeled 12-18 months, but I'm listing it as size 80. It was a gift, but my child has outgrown it, so it's never been used. It has a zipper instead of buttons, making it super easy to put on and take off ◎ It seems comfortable for the coming season, as you can just throw it on over underwear and go out ^^ Please check the product condition in the images and purchase if you understand that it is a used item and has been stored at home. If you are concerned about details or are looking for something like new, please do not purchase. I may fold it and compress it in a zipper bag for packaging, so please understand that there may be creases. Also, there may be oversights due to amateur inspection. If you have any concerns, please comment before purchasing and make sure you are satisfied before buying. ★ I also have baby clothes and children's clothes for sale, so please feel free to ask about combined sales ☺︎
