This was purchased at the same salon when I bought a set of Pasio shapewear. It's black, so it doesn't look like underwear, and I don't mind if a little bit of the waist is visible. The size is adjustable, and it fits the body, doesn't hinder the movement of the waist, and is comfortable to wear, while also providing support. The back hook type may seem difficult to fasten in the front and then turn to the back, but if you put a smooth camisole in between, it will turn smoothly! Then just take off the camisole. Recommended. Please check the size on the tag in the image. Thank you for looking.
