You Save Shapewear for Weddings and New Year's Eve

Slimming garments can smooth out lumps and bumps—and needn't be reserved for special occasions. Heather Thomson, founder of the shapewear brand Yummie by Heather Thomson, says that while your shapewear should fit snugly, it's important that it's not too tight, to avoid certain health concerns. "Sizing down will not make you look thinner; it will only make you more miserable—I can't stress this enough," says Thomson. "You know you have the right fit when you can breathe and you're not standing in the corner unable to move at a party."
