H&M Sleeper - Cookie Monster Size 80, but it's long, so I think it can be used for quite a while. There's a zipper on the side, making it easy to put on and take off. The fabric is very warm! I bought it on Mercari, but my child didn't like sleepers, so I didn't use it. There are no noticeable stains, but there is some aging due to home storage. Please consider this item, understanding that it is a used item. When shipping, I will compress it slightly, so please be aware of that.
