I'm always on the lookout for fashions that I might be able to make at home and/or recreate at a lower price. Here's an easy idea. Buy a bright t-shirt and paint some bright comic book types words on it. Here's a guy from a street style website who has the look. It looks like something that might have been made by a great pop culture designer!
This design looks like it was airbrushed. If you are like me and you don't own an airbrush, you can sometimes create a similar effect by putting fabric paint in an old spray bottle.
