Purchased for my friends daughter to grow into (she's currently 6) but she doesn't seem to have any interest, and told me I can sell it. I don't really understand kid sizing, but, as she's 6, and it mostly fit her at a size 8, I'm going to assume a normal 7 year old can fit into it, or a small-framed adult. Measurements are pictured. There are spots where you can see the previous own put pins in, but not terribly noticeable.
