The size is 140. This is a set of two of the same size. I used to dress my two sons, who are two years apart, in matching outfits. The waist is adjustable with elastic, and the hem can be folded up to adjust the size. Although it's size 140, I had them wear it when they were around size 120-130. I only wore them a few times, so there is no fading or noticeable stains. Please understand that these are used items, stored at home, and have been inspected by a non-professional before purchasing.
