S&B gurus I need your help please. I am a size 14 and will be wearing this dress www.phase-eight.com/fcp/product/phase-eight/occasion-dresses/sinnita-sequin-full-length-dress/203621351
To an awards evening for my husband's work. I need underwear that will smooth out all my lumps and bumps, particularly my tummy and love handles 
I don't want to feel uncomfortably restricted but do want to look my best. I can wear a normal bra underneath.
Thank you
