Basic T-Shirt, White, Adult L
Have had Zazzle complete a number of T-shirt projects in the past. This one had several design elements. It was well done. I will work with Zazzle again.

The T shirt seems to be made from decent material but appears to be an irregular t-shirt sewn and stitched. .

The shirt is good quality and fits just fine, but the colors of the printing are not as bright as in the sample photo. Not the best. The colors are a lot brighter in the sample photo; when I received the shirt they appeared faded. The red looks a little more pink and the blue is a lot lighter. N.B. I did not wash the shirt yet.
