I bought a new garter belt, mail order, many years ago and while it wasn't a snug fit it seemed OK. With the wife out of town I felt daring. Dressed in my finery I set out after dark to a nearby Mall. Not being very brave it was my intent to simply walk around the outside of the mall and then back to my car an away home. I parked away from the bright lights and walked toward the Mall entrance. After about a hundred yards I felt the garter belt start to slip over my hips. Garter belt with panties were suddenly around my thighs. I imagine I cut a comical figure as I hot footed it back to the car trying to hike up panties and belt. Drove sadly home dejected over a lost opportunity.
Experience is something you don't get until just after you need it.
Hugs to all.
