This is a coverall from H&M. The official size is 55, for 1-2 months, but my standard-sized child wore it until 2-4 months. It's in beautiful condition, having been worn only a few times indoors. The fabric is quite sturdy, and both legs can be opened with snaps, making diaper changes easy. It has been washed with only a gentle detergent after each wear. Sleeve Length: Long Sleeve
