I wear a 17 neck 34 sleeve shirt which is usually an XL size. The "classic" cut of the shirt is very loose in the waist, and I usually choose something slightly fitted. I ordered this Henley in size XL. It had the right sleeve and torso length, but was too tight. It looks like it was made for someone who is low on fat and doesn't work. Unfortunately, I have a bit of both and ended up gifting it to my dad.
