Per usual, only much heavier weight cloth!!!

My last order was early last summer and you didn't yet have the heavyweight option - nice surprise! However, my last order, I ordered a large, which is my size, in the lighter weight and it was too small. So, on my future orders (last year), I ordered XL and they fit perfect. Of course, this time, I decide to try the new, heavweight shirts and assume (there's that word - "ass-u-me") and order a black shirt AND a white shirt in XL, with a new design that I created. They came out AWESOME but are like a tent on me! Should have asked first! They're 100% Cotton, so hopefully, they'll shrink some??? "Crossed Fingers"
