"The Chest harness fits chests up to 60" and also fits around pillows and thighs. The 4 point adjustability of the harness make it easy to get a custom fit. It also comes with three different sized metal O-Rings (1 1/2 inches, 1 3/4 inches and 2 inches) so you can easily change the ring to accommodate your favorite dildo or toy with a flared base."
If you're crafty, you can probably convert this into a traditional waist harness.
I'm asking $15 for it. Please e-mail me at email@example.com if you're interested. Thanks.
