Authentic waist trainer corset. To train the waist you need a strong non stretch corset with double spiral steel boning. Sounds uncomfortable but actually much more comfortable than a tight stretchy garment. This one is a 20 inch for a 22-24 inch waist. Matt black satin with heavy cotton lining, heavy back lacing and modesty panel which sits under the lacing at the back. Instructions on how to fit and look after corset will come with it. My mannequin obviously can't squash in as she is a fixed shape. On a person the corset will pull tight at the waist area.
