Hi all! Hope everyone is well. My son, 13 & husky, is is a boys 18/20 just firting well but what comes next? I found out that mens small underwear is actually smaller than boys 18/20 so I would assume mens meduium but I am afraid to order. What about shirts& pants. He does not like to try one clothes. I really would appreciate all and anybhelp with this. TIA
Men's sizes work by length and waist size. Measure his waist to figure out his size.
