Rhythm Lingerie Ad, 1946

I've worn these things, but never liked nor understood them. Ads never show the bra you need to wear with them, because the combined effect never looks good. Yet somehow it's never occurred to anyone to make a full slip with a bra built in. Feh!

(Tough to make out the illustrator's name: "Brigham... Girdol" ?)
