I've got an unusually (for me) clinging black dress...although I'm a size 12 the rigours of age/children/laziness are a bit (quite a lot) unforgiving. I'm thinking that the time has come for that body shaping underwear they have now. So would it give me that smooth and shapely in a clingy dress thing and would avoid vpl ? What sort of shaping wear Is best? Is it incredibly uncomfortable to wear? I'm a complete novice in the ways of shaping underthings
