Overbust corsets are non-conical, non-bra overbust corsets popular for modern wear. Historic periods of use range throughout the Victorian and Edwardian, and include all manner of piecing styles involving panels and gores.

This is an overbust corset I made for myself.  It has a brown raw silk cover, yellow ribbon embroidery gears, and a split metal busk.
