Just got age 12-13 delivered for my quite tall 9 year old son normally he would be in age 12 but this T-shirt I find is even smaller again it fits him like it’s a bit snug I could probably get a couple of weeks wear out of but I haven’t even washed it yet so I’m thinking if I allow 10% shrinkage this will be too small after the 1st wash, will probably return or give to my nephew as they are really small fitting and not like a regular fit on my son.
