This is a type that allows you to put your hands out, and because it's a lace knit, I adjusted the inner clothes to suit the climate and used it. I used it twice, but my child doesn't seem to like swaddles, so I haven't used it since. I think the size is free size. (I've selected it for now because it's a required option) It's made of a stretchy material, which is also recommended for preventing your child from scratching themselves. There are no noticeable stains, but it has been used, so please consider it as a used item.
