Kitten hips. No, not the furry kind — the “lithe young American” kind, as described in this vintage girdle ad published in Harper’s Bazaar, 1946.

You feel and look as if you’d just stepped out of a success course when you step into Carter’s “Mouldette.” The entire beautifully molded back is made with new synthetic elastic. Carter’s own Sweetheart panel flattens the tummy. Every seam’s a scheme to give you that lithe young American look.
