FANTASTIC PURCHASE! This waist cincher is both comfortable to wear and gives me the shape that I am looking for. I am a cosplayer who spends a lot of time wearing figure hugging and spandex costumes, which can leave me a little self conscious. My body is a bit of a rectangle shape, so this shaper creates a wonderful, comic book type hourglass figure. I have worn it for 8 hours at a time several different times and each time I was comfortable all day. The key to comfort is ensuring you read the sizing information, measure and ensure you order the correct size based on your measurements. Though it can certainly be tempting to go smaller, hoping for an even smaller shape, it can be extremely painful! With the right size and using for the right reasons (creating a slimmer figure under clothing, as opposed to hoping this will help you lose weight) this Waist Cincher is an amazing buy!
