Real steel boned waist underwear corset from transparent mesh and cotton. Real waist training corset for tight lacing. Authentic corset on steel bones, tightening your waist up to 6″. Perfect design for plus size tight lacing, for real waist training and underwear. Custom sizing for additional waist reduction is available. One of the main benefits of a waist training with this mesh corset is the lack of a busk. A busk is a metal piece that is inserted into the front of a corset to help keep it closed. This can be uncomfortable and can also restrict movement if you are using it for more than 8 hours a day. This Waist training mesh corset is designed without a busk which allows for greater flexibility and comfort.
