About T-Shirt Design
If you like shirts that actually have some personality, Irish 30 T Shirt is a good example. It fits really well with St. Patrick's Day, but you do not have to be obsessed with that stuff to enjoy the joke.
This would be easy to give as a gift for parties, parades, or any random day when you want to make someone laugh. It has the relaxed feel people usually want from novelty shirts without getting too complicated. It fits nicely with novelty t shirts that are meant to be fun first and serious never. It is simple, funny, and easy to picture on someone who likes this kind of humor.
