kkards, this turned out to be a great tip for me. I have the middle weight shift, straight hips and a small butt, and I've been going crazy with pants sliding down. I have a hard time finding regular belts that I like and will work. I bought one in navy and it is great so far. I love the way it adjusts. Now I want some in several colors.
Years ago I bought an invisible belt--the plastic kind. Even though I soaked it and hung it outside in the sun for days, it still had that horrible chemical smell and I couldn't stand to use it. It had other flaws too.
So thank you for bringing this item to my attention!
