Princess Slim waist cincher for waist shaping. It fastens with a 4-level square hook and uses stretchy, resilient material to shape the abdomen. The design is based on ergonomics, so it fits perfectly but is still comfortable. Wearing it will naturally help you achieve a beautiful waistline♪ I also wore it for lower back pain, and while it provides firm support, it doesn't feel overly tight! It's easy to put on once you get used to it. I'm decluttering, and due to the nature of the product, it cannot be resold after opening, so please understand that no claims or returns are accepted.
