Update - As soon as I posted the below review, iTailor got in touch with me and offered to replace the shirt that did not fit free of charge and even to refund the $79.00 in addition. That is great customer service! I looked up their terms and conditions before posting my original review which are: "-Every product is 100% individually tailor-made and handmade according to the customer's preferences. Hence, we DO NOT accept returns for any reason except production error." There is nothing that I could find anywhere on their site before posting my review that made me think that I had any leverage, and so I thought I was just stuck with the too small shirt. Wow I have rarely been so happy to be wrong.
Luckily I started with just one shirt, because although I thought I followed the measurement directions to a T, my shirt overall is too snug and too short, So, I guess I'll look on the bright side and be glad I'm only out $79.00. Because it is custom made, there are no returns, and because it is too small vs too big, I can't even send it back to have it altered (not sure I would bother anyway). The material and workmanship look perfectly fine. I got exactly what I ordered as far as colors and the rest of the choices, but it doesn't fit. So lesson learned, I won't order custom (non-returnable) clothing on line again where perfect measurements are critical to success.
