I finished a new article describing how to add a triangular or trapezoidal gore into a fabric panel. No one method will work for all situations, but where possible I mention alternatives while describing the process I used for one particular corset.
Why does this matter? Well, if you have a corset, but the bottom or top is just a little too small, you may want to consider adding gores to re-create it as a unique garment designed to fit you. In eras where corsets were a common (or required) undergarment, this kind of modification was a common approach to changing fashions, or fitting an existing corset to a new owner. Many extant corsets underwent modification and alteration, because it takes less time and is far less expensive than the materials required for an entirely new corset.
Corset Alteration - Adding Hip Gores It is posted to my personal web site. It is far too long to be practical re-posting here on LJ.
