This is something I ought to know the answer too, but I don't. So be gentle, please.
For some time I've been wearing XL undershirts (and, just for the record, size L OCBDs and XL polo shirts), but I'm losing weight (over 20 pounds thus far, with another 40-50 pounds to go). Then I'll be able to wear size M shirts for the first time in way too long (and get a new, more Ask Andy-ish wardrobe to boot)! Problem is, while I think I wore size M undershirts back then too, I don't remember for sure. And I've since come to realize that I don't know what the rules are (if any) for undershirt size! Are you supposed to wear the same size in undershirts as you wear in shirts, or larger? Thanks in advance.
