This is a baby outfit from Hakka Baby that I loved and used to dress my baby in. There is no size label, but I think it's 60-70. It's a little big if you think it's 50. It's 100% cotton and perfect for the coming season. There are no noticeable stains, but it has been used. Some of the paint on the buttons has come off. The tag is also rubbed, and there are marks from where a sticker was removed. Please understand this before purchasing.
