Tatiana Bee, from London, has a nice side hustle going on…using only her underwear.

Through the Sofia Grey website, she’s discovered people will pay big bucks pawning off her used, and presumably unwashed, underwear. For just over $55, you can get a pair of “24-hour wear” panties from her personal collection.

Just from that, she pulls in close to $2,000 a month, and has even surpassed the $5K monthly mark a couple of times.
