My son is 14. I ordered 18 based on the reviews I read. He is tall and thin. The suit was a little big as I expected but the length of the pants was perfect. He has long legs and arms so I needed the length. I just tightened my waist a little and it was perfect. The shirt was huge. The collar was huge, the neck was also thin. I ordered another size 16 shirt online from Calvin Klein and it was perfect. Also, you definitely needed a belt. I also ordered this online and everything came in perfect condition! You can't overstate in this suit.
