If there’s one thing most celebrities swear by on the red carpet — even if they don’t admit it — it’s shapewear. These highly functional pieces can be crucial to an outfit, lifting up and sucking in anything that needs some smoothing. And who doesn’t love that? But with so many options available to choose from, it can be difficult to know which styles work best under each outfit without adding bulk or bulge in the wrong places. That’s why we’ve picked out our favorites from the industry leader SPANX — all of which are under $100 — and matched each one to the outfit they work best under.
