Tomorrow I'll post a list of supplies needed to make the 1911 corset. Until then, I'll leave you with this advertisement for Warner's Rust-Proof corsets.
This was published in The Washington Herald, February 19, 1911, as part of a full page ad for the Palais Royal department store. If you want to get lost in period corset advertisements visit the Library of Congress website. If you are like me you'll completely loose track of time. Have fun researching!
