Designed shirts for my sisters 21st birthday. Easy to design, the style print/font size looks great on all shirts (I think they adjust accordingly). Customer service was awesome!! Super helpful. VERY PLEASED!!!

21st Birthday Shirts
I had asked an artist to design three t-shirts for my daughters 21st birthday. The designed didn't get to me until only days before we were leaving on her trip to celebrate. RushOrderTees did a great job of not only making a great quality t-shirt but was able to get them to me super fast. These were a big hit for my daughter who wore them all over universal studios. Thank you again so much!
