I bought this at a Korean clothing store. The size is 7 in Korean sizing (equivalent to a Japanese size 100). The ribbon can be tied in the front or the back♪ I'm selling it because my child has outgrown it. Please refrain from purchasing if you are sensitive to items that have been stored at home.
