I try to be the best seller I can be–I always send a photo or two of me wearing the panties/bra/what have you, and I also send a photo of the package which will be sent to them. I also ask for critical feedback–I want to know if the person is unhappy, so I can try and make it right!
For me, this is really about enjoyment. I want people to enjoy using the panties I wore for two days, I want them to enjoy the bra I once wore. That makes me so happy 🙂
As for bogus buyers, I’ve had a few. You just brush them off and keep going.
