I've been wearing my linen casual shirts on a pretty consistent basis. I sized down and out the dryer they fit a bit too snug in chest but loosen up to the Perfect Fit in about half an hour. again, I'd go with what's closest to your shoulder size to see if you should size down or not. love the dark grey and blue with jeans and tobacco suede wingtips. really wish uniqlo would come out with more plaid patterns or a burgundy.
