My grandchild came over only once last Christmas. The size is probably 90. It's a two-piece set. The pants have an elastic waistband. The fabric is thin. Length of top: 30cm Sleeve length: 25cm Pants length: 35cm. These measurements are approximate. After wearing it and washing it once, some red color has slightly transferred to the white sleeves. Please consider purchasing if you understand that this is a used item.
