These days it appears as if women will go to great lengths to achieve the hourglass figure with a large bust, small waist and curvy hips. The latest in these attempts is the waist cincher — a compressive undergarment that’s akin to a girdle and meant to “train your waist” to be smaller. You know what? Beyoncé has one. Scarlett Johansson and Marilyn Monroe do, too. Kim Kardashian also has shared a new Instagram shot of herself, and she’s all corseted up. Now, you are so excited when receiving a type of waist cincher that you have booked from Amazon and want to try it immediately. Hold on! Please be sure about how to wear a waist cincher properly first!
