The is a one layer cotton coutil corset, sewn with machine using period techniques described in The Fashions Of The Gilded Age by Frances Grimble. The pattern is based on the c. 1873 corset from Corsets and Crinolines by Norah Waugh. The corset is heavily corded with cotton cord, which stiffens the corset wonderfully.
The bustle pattern is based on the one in Corsets and Crinolines, only drafted a little lager.
The petticoats are stiffened with flounces and cotton cording.
