This is a set of sizes 110 and 100, both of which were worn when the child was wearing size 90 or 100. The scalloped pants have an adjuster. I loved these and kept them carefully, but I don't think I'll be wearing them anymore. All items have been worn a few times and are in good condition, but the light pink Kyoto-limited sweatshirt has some slight stains as shown in the last photo. Please refrain from purchasing if you are overly concerned about details.
