Glamour Magazine 1944 - It's "Good Behavior" that counts

For slips that is. Especially if we are talking about Movie Star Slips...this model is "Winged Victory" and it "behaves well when you stand, sit, walk or run". (I wonder if they actually tested women running while wearing these slips? I think not.) But the illustration is lovely, she looks like she could fly. (Bet they didn't test for that either.)
