My daughter wore this when she was around size 90 to 100. It's been worn by a child, so it has a used feel. A lot. There's also a name written on it. But it's cute. I often got compliments when she wore it. The pants are from Uniqlo. Mezzo Piano runs small, so I think a size 100 item would be best for a child around size 90. I'm selling it at a low price, so please only purchase if you're okay with the used condition!
