Wear a green shirt on Thursdays if you are a lonely single looking to score some action for the upcoming weekend. The green shirt will signal to those interested what your intent for that weekend is, and possibly help you hook up with a lovely individual.

A t-shirt made with regard for the future. That is, a shirt not just made with today in mind. A green t-shirt can be made using sustainable and socially good practices and it can also have messages related to “being green.”

Bright green tee shirts.
Church groups like to wear them so they can find each other on field trips.
