Calling on advice from Spanx users! Am usually a small size 8 but have 17 week old twins so have a few post natal lumps and bumps. Have a wedding and 3 naming ceremonies coming up and think it's about time to invest in Spanx or similar but I'm really confused as to which. Hide and Sleek was well reviewed but costs twice as much as Higher Power and seems to do much the same thing (or not?). Which would anyone recommend? Thanks in advance. (may well soon be posting for dress advice too!)
