I ordered the Youth L shirt for my son. The label says size L 14/16. I couldn't figure out what letter size corresponds to age size, so hopefully this helps someone. My son is 6 years old and usually wears a size 10. This size L 14/16 fits him a bit baggy but not big enough to look like a dress. The color of the tie stays the same after a single wash. The neck hole is fine for a child but quite small so definitely not for adults (I tried it on).
