That's why I was looking for single-colored cotton shirts for my child on which cartoon characters could be embroidered. The fabric has some horizontal stretch that I had to account for, but other than that they're great for what I do. They are undersized. I ordered a size 9-10 and while they fit my 8 year old perfectly at the moment I originally wanted them to be a little oversized so they would last longer.
