Corsets serve one primary function: to give the body a "fashionable" shape. The rebellious body tends to resist unnatural shaping; therefore, the main requirement for a corset is strength. Aside from the shapes of the pattern pieces themselves, the two factors involved in a corset's shaping strength are: the fabric of the garment and the stiffening used.

You must discuss your design options and fabric variables with Kirsten before a final price is arrived at.
