I learned there is a wallet for Bras called a Rack Trap.
I suggest females that like to put money in their bras get this because I really hate getting sweaty money because I just happened to be standing behind a female that decides to pay for something with her tit sweat dollar bill and the cashier doesn't want it so they give it to ME as change!
Would you like it if I put my dollar bills in my underwear and you got handed some ball sweat soaked bills?
Be considerate of others and get a Racktrap
