"The Charleston Slip-Ons" (Modern Weekly, October 23, 1926)

 Modern Weekly was, as it's name suggested, a magazine for aspiring flappers.  It contained fiction, beauty tips, guides to the latest dance steps, fashionable gossip, and of course, fashion.

How to be slim though petticoated!  That's quite a problem, with our new dancing frocks demanding a frilly skirt beneath them and a slim outline above them.  But here it is—a solution for you—a petticoat of four fluttering, picot-edged panels, joined with evening knicks to a long bodice, and made from our Free Pattern of the "Charleston Slip-ons."

Who would have thought flappers wore such complicated garments under their dresses!  The quite detailed instructions for making up indicate that right leg of the knickers was made to fasten with buttons from waist to knee.  The top of the bodice was held in place by a small piece of elastic under each arm.  (I still haven't quite worked out how the wearer was meant to put the slip-on on.  Presumably she stepped into it and pulled the whole thing up, with the elastic allowing it to be maneuvered over her hips.)  The magazine recommended 2½ yards of crȇpe-de-Chine for making up the pattern.

Modern Weekly managed to outlast the 1920s—barely.  Its last issue was published in 1936, a mere ten years after it started.  "Modernity" was clearly not the selling-point it once was.
