hanes and champion does good plain shirt, or try janpanese brand like flat head or full count Zimbabwe cotton

@SepticSef:

i really like buzz ricksons and the real mccoys sweaters but unfortunately they are too short.the overall length is usually about 26" in xl but the chest size is gonna be around 45" which is way too big.i do however like the reigning champ sweaters.they seem to be cut a bit more slim.
does anybody have one or can recommend any heavy duty crewnecks with a moderate slim cut?

i think the vintage brand will not fits your request anymore, cuz buzz and rm got the best cut in vintage sweater, so i guess you should try some fashion brand like cdg…
