The Urban Dictionary Tee
Not only was the product exactly what I expected, I was well informed on the shipping process in a seamless and timely manner!
The T-shirt was a birthday gift for my girlfriend and she absolutely loved it.
Happy that this tee is comfy and fits well. I wish the sentence was on the back too.
