This is a 2-piece set consisting of a thick, long-sleeved cutsew and a skirt from Kumikyoku. The size is L, which corresponds to 120-130 cm. The skirt has pockets on both sides. You can also enjoy coordinating with your sister by purchasing the S-sized item, which is listed separately, for a matching sibling outfit! I don't see any noticeable stains or dirt, but please forgive any oversights as this is a personal inspection. We do not sell items separately.
