If you want the world to not know how much money you don’t have then this could be the shirt you need. (confusing isn’t it?)
On this t-shirt is says “Secret Zillionaire” and below it a round with a dollar sign in it.
Of course if you wanted to be a secret that you have a lot of money then you would not wear this shirt and I don’t think someone every has a zillion dollars so you probably don’t have that much either but is sure is a fun t-shirt.
