Art Deco 1920s Corset Ad

Another corset ad, this one from a shop on Fifth Avenue in New York in the early 1920s.  It doesn't actually show the corset, but it's so cute!
"Goodwin corsets provide the most desirable foundation for the gown."
So-called "foundation garments" were a standard part of women's wardrobes for decades to come, well into the 1960s.  How do you think Joan Holloway looked so fabulous gliding through the office on Mad Men?
