From Truly Victorian:
This corset pattern is based on the styles seen in 1903. It has the low, full bust and long hip needed to create the "pigeon breast" look that was popular from 1902 - 1909. The corset is available in three heights; high bust, medium bust, and low bust, and comes in bust sizes A-DD. The hip is in three lengths: long, medium, and short. Also included are patterns for a hip pad and bust forms, which are needed to help finish out the figure. The instructions are for a single layer corset, which was the most typical of the period.
This pattern is recommended for persons with previous corset making experience.
