Kim Kardashian first had the idea to launch a shapewear line over a decade ago - it was sparked by the fact that she always found herself cutting, sewing and dying her existing solutions. The result of dedicated fabric testing and development, this thong is part of the 'Core Control' line and is designed to sit undetected beneath clothing. The label's team say it "smooths and tightly contours" your tummy with a supportive, compressive fit. The double waistband and strip of silicone at the back keep it in place.
