Mine is 5 years old. He is 45 inches tall. (I think he's tall for his age.) I had a hard time finding better underwear for him. (He doesn't like tight underwear. He likes being naked too, so he wanted to buy something sensual. like loose and "naked", but still wear something. π) I'm glad I bought them! I have size S for him and they are just perfect for him! I will buy more! 100% recommended πβ€
