The CS-411 Double Steel Boned Standard Length underbust corset from Orchard Corset is a Silhouette Level 2/3 (extreme curves) waist training corset. The 411 has 22 spiral and flat steel bones and is designed for average torsos, however longer torsos can wear this corset quite well and find it can be more maneuverable than our 426. The bottom and top edge have subtle contour. It is available in satin, leather, brocades, plaids and pinstripes in many stunning colors and patterns. The black satin comes in sizes 18-46, all others are available in sizes 18-40.
