Our Valentina Steel Boned Underbust corset is made of a heavy weight brushed satin, which has a lush sheen and elegant feel. There are 14 bones in all, made of high density German steel. Ten are spiral bones for four-way movement and four are rigid steel bones for two-way movement. The corset has 6 garter loops. This waist reduction this corset is designed to achieve is between 2 to 5 inches. Underbust corsets are versatile and can be worn with a black bra, blouse, tank top or lace teddy. If you’re not used to wearing corsets, we recommend getting dressed a little early the first time you wear it. Tightening the laces and hooking the busk might be a little tricky if you’ve never worn steel boned corsets before. The results are worth it though – you will love it!
