Well I don't wear a collar in the strictest sense, I have a weird thing about anything touching my throat. My Master has me wear a necklace with a DNA helix design on it. The necklace pertains to both our careers and our connection. Also from time to time I've worn nipple clamps out, underneath my clothes. I'm not sure if that would count as gears. Also I've been made to wear a few of my role-play costumes out. Nothing too sexy or that would get me arrested, just normal type clothes that aren't quite my individual style I guess. And wrists cuffs with a leash attached in public, which can be surprisingly discreet when necessary.
