Ordered a small and it was about halfway between small and medium (by my subjective standards). It's not a bad fit, just looser. Good for if you (legally) concealed carry, actually. After that, I ordered an XS just to see. It fits a bit smaller than what smalls normally are. Sort of a 'slim fit' kinda deal. Both are great and feel great. Very soft and seem durable so far. Very happy with them, just not quite the same sizing as I expected.
