I have a double strap stle harness called the Jaguar. I am NOT a size 0, but I would think any good leather harness would fit. Mine will go down to fit a size 29 inch hip size, and if you needed it smaller than that you could just punch a couple more holes through the leather. I would think that a double strap (think jock strap) harness would be able to fit just about any size given that the leg straps can be tightened to fit legs that are incredibly thin. Also with a leather harness you don't have to worry about it tearing if you do need to punch a hole through it.

Hopefully someone of that size (or at least closer than me) will be able to give some advice from actual experience. Best of luck to both of you in finding something great!

I have a partner who's very thin, and they actually have trouble with harnesses being too large. What you might want to do is get basic leather harness, a leather punch ($10-15 at a hardware store) and punch holes for her size.

My husband and I engage in this type of play all the time. We both take turns playing role reversal games and it is fantastic! My husband is totally straight but will allow me to turn him into a gay cross dressing sissy for the night. Pumps, lace, make up, wig the whole out fit. I usually dress up and play the male role or put on my leather out fit and turn into a real harsh fem dom. I use a variety of realistic strap on penises on him and force him to take it like a woman in every position that you can imagine! The orgasms for both of us are the greatest! I am sure if you go to the right dating site you will find plenty of women are very interested in this type of play and would love to engage! Please be careful though.

Wish there were more of you in the world! Although I can't help out with your fantasy, I am going to try it on my (straight) boyfriend! WOOHOO! We are both super excited! I'm ordering the Jaguar and debating between several accessories!
