I’m average height, and I still feel like shirts are always too short. I constantly have to retuck my collared shirts, because they become untucked if I ever put my arms over my head.
XL feels like I am wearing a tent and it still doesn’t stay tucked.
Mens Large cut long for tall people is what I buy for anything to be tucked in. I have a lot of LT (Large Tall) shirts from Ralph Lauren. They had a very good big and tall section at their Opry Mills store for many years but it seems to be less and less so since Covid. I guess their website is the best bet. I get LT undershirts from Hanes. I have some LT shirts from Cabelas and Filson. I’d love to try a Mens Medium cut long but I have never seen one.
