This is a set of Mikihouse items: a size 90 dress and size 80 pants. The dress feels a bit small for a 90, so it might fit from size 80. The pants are short, around knee-length. There are no noticeable stains, but they were used as everyday wear, so please be aware that there is some wear and tear. They can still be used, so how about the set? A girl wore them for a year, but they weren't worn very often, maybe around 30 times.
