I don't even know how to answer that????? I guess that depends but I would say it would fit a small 14 year old right down to a large 8 yr old. The tag says Youth small??? Hope that helps.
Fyi, to anyone reading the last comment. That seems a bit smaller than it is, considering a 13 yr old was wearing it just a few weeks ago. I think most 8 yr Olds would be way too small for it.
