Desperately looking for a snap on handle like you have in the back of your harness in the picture of your birthday boots ... Send me in the right direction ?
Surprise! They’re actually suspenders!
Most suspenders can convert effortlessly into a makeshift harness.
I do it all the time with my leather suspenders (here’s what they look like as suspenders). I’ll get to a party wearing them as suspenders, dance for a bit, then convert to sexy harness mode…outfit change!
My leather and rubber suspenders are both from Mr S Leather. If you can visit them in person, do so…they fit you at the store and they customize the length to fit perfectly (or sluttily, whatever you want).
