Maybe that’s a pipe dream..... I’m after something that smooths from waist to thigh, and holds my post-baby bump in! (Very post-baby, they’re three and five now!).
I have to wear a bridesmaid dress this summer and it’s VERY fitted, and made of satin - it shows everything! I’m a healthy weight and a curvy pear shape, so I’m not expecting to drop inches, just to smooth everything out and hold in my tum which is SO visible in this dress! 
Can anybody recommend good shapewear that won’t roll down, and also crucially will still enable me to sit, eat and dance (if I’m feeling brave)?!
