About T-Shirt Design
There is nothing complicated about Rub Me, For Luck T-Shirt, and honestly that makes it better. It has a clear St. Patrick's Day vibe, which makes it easy to picture as a gift or something to wear for fun.
It makes sense for parades or St. Patrick's Day, especially if the person already likes this kind of humor. If you like to buy t shirts because the saying actually matches your personality, this one makes sense.
It feels casual enough for normal days but still has enough personality to get noticed.
