I'm going to a dinner dance and have a party frock under which I plan to wear some seriously smoothing and holding-in underpinnings. Tights are no good - they give me a ridge round my waist. Do hold-ups stay up? I'm planning on dancing til my feet ache in my killer heels so I don't want to have Nora Batty-esque wrinkles.
Any recommendations or brands to avoid?
