This is a babyGap overall skirt. The size is 12-18 months, which is equivalent to 80cm in Japanese size. I only tried it on once and then washed it. Although it's labeled as Japanese size 80, it didn't have much room around the tummy and felt a bit tight, so I'm selling it. It might be better suited for a child who wears around size 70. It's very cute, so I hope someone will wear it.
