Thank you for viewing! This is a 4-piece set from Mezzo Piano, size 160cm. All pants have adjustable waists. One pair is fleece-lined and thick. No individual sales. Other sizes are also available. Although there is some wear and tear, there are no noticeable stains from a girl's use. However, since these are used items, please purchase only if you are not concerned about the feeling of use or overlooking any stains. To reduce shipping costs, I will fold them compactly and compress them for shipping.
