This 100% Columbia Grade latex Waist Trainer is one of our most popular shapers. Not only will it help correct your posture, it will help shape your waist and lose weight and inches through compression and sweat. The 2 in 1 waist trainer can be worn solely as a body shaper, helping you to achieve more curves discretely under formal or informal attire, or as an essential gym accessory aiding in your weight loss goals on your fitness journey. *Note: Waist Trainers run small!!! Please reference the sizing chart for your correct fitting, particularly waist measurements. A waist that measures 30 in is roughly 77 cm, which would translate to a size Large Waist Trainer.
