I love the tee-shirt. Unfortunately, I equated XXL with 2X so they fit a little tighter than I prefer. That's ok, though, I still wear them. :o)
I followed the advise of a customer about the sizing chart, and following it, my first order was way too big. I usually wear a medium, but ordered a xlarge on a previous order.
I ordered again, using my regular size, M, and it fit perfectly.
Order your usual size or one size up for a loose fit.
