I just saw an informercial for the Trendy Top- it's the top that's not. It is a piece of Fabric that you put around you waste that makes it appear as though you are wearing an undershirt. It prevents crack from sticking out when you bend over or sit down..... Why not just wear a cami or long tank underneath? I really don't wear pants that show my buttcrack when I bend over. If I am concerned, I wear a long tank. I would feel silly wearing something just around my waste. Anybody ever try it?
