It is made of quality fabric, has spiral steel boning and has a busk with a lace up back. This corset tightens up very well, holds me in all day, and is quite comfortable.this is good for those who have a bad back. it will make you sit slender and fix your posture if you have problem about it. I am very pleased with this corset.it gives me the look of having a nice shape body. my husband likes it everytime i wear it. and it gives me more confident to show off my shape in public without noticing im wearing this.
