What size for a boy 5'3, 92 lbs?
Go to: baresports and check out the sizing chart. My son was in a 12 last year and I will be buying the same suit in a 14 this year. It is a great suit I have the same one myself.
I go this for my son last year who at the time was similiar size and went with a size 12. He tried it on and it fit fine. Ironically that was the only time he wore it as his athletic activites at school took away from opportunity to swim in cold waters. He has long since outgrown it and I would be willing to sell if you confirm size 12 is what you interested in purchasing. Please let me know if interested via e-mail. Thank you
