A few hours---and mojitos---later and I was giggling and wiggling in a bathroom stall telling my powerful secret to a stranger in the next stall. My only gripe was that they felt too warm under my dress, although I reminded myself that my hot (feeling, not looking) knickers were working very hard to keep things in place under there! The extra layers would be a welcome warmth on a wintry NYC night but not on a mild and almost muggy May evening. All in all I was less conscious and felt great, which we all know translates to looking great. I haven't worn my power panties since but it's good to know I have a secret weapon, should the need arise (or rather inflate!)

Thanks Spanx.
