Do the heattech undershirts shrink? I'm usually a size S but I'm considering buying XS as I am super skinny (5' 10" 130 lbs) and so that it doesn't make my dress shirts look puffy. I wear undershirts and yes I know they are not SF approved.
What else is to die for at Uniqlo so I get the free shipping? I don't have one near me so I've never been in one but read many good things about them.
Polyester usually doesn't shrink and I have not noticed any of my heattech shrinking.
