Concave Rib (U-shape)
Also called a smooth, sloped, or gently curved silhouette. A continuous line from underbust to rib to hips, without a dramatic dip in the waist. This can create an early Victorian style silhouette. In modern corsets, this silhouette is usually seen in corsets of relatively gentle reduction.
Straight Rib (Conical)
Also called “ice-cream cone” shape, because of the conical ribs. This style of corset compresses the lower (floating) ribs, and tends to create a 1950’s style silhouette.
Round Rib (Hourglass)
This silhouette is not quite conical, but not dramatically cupped in the rib – rather, it is somewhat gently rounded or convex. This style may compress the floating ribs slightly depending on the waist reduction.
Very Round Rib (Cupped)
This silhouette cradles the lower (floating) ribs without much or any compression, and dramatically nips in at the waistline. This style may be more comfortable for those with flaring or rigid ribs. This type of corset may create a narrow band of pressure around the waistline (below the ribs).
