Saw the Engineer shirt on line and searched for a vendor who sold it and found Chummy Tees. The message certainly rang true to the engineer I'm married to (LOL). I was very happy that Chummy Tees had measurements to help with sizing. I pulled out a t-shirt that I knew fit my husband well and measured it to match against Chummy Tee's measurements. I have not given him the shirt yet as it is a Christmas gift but I think he will love it. Ordering was a breeze and the shirt came quickly. No problems! Thank you Chummy Tees. I can't wait for Christmas Eve to give him the shirt.
