I see no problem with it. Heck, I'm 23 and I don't remember my female classmates my freshman and sophomore years of high school looking that good. I think girls are physically maturing earlier now than they were before. I've seen a 14 year old stand next to a 19 year old and pass for being older. It's almost scary.
If you are going to play that field, be sure to check ID to keep yourself out of hot water!
