The Swan Look is a Young Look

This ad is from 1948 edition of Woman's Home Companion for Swan Pure White Soap. The ad is titled 'Feel Swans exclusive Super-Creamed Blend!' and goes on to pronounce; 'Feel it in the smoother cake! Feel it in the creamier lather! Let Swan keep your skin looking younger!'

This image is part of that ad. It looks to me like she's wearing a swimcap as a hair cap with the exception of the tie ends under her chin. It even has the water guard ribbing. I'm wondering if these were the pre-cursor to the swimcaps of the 50s? Certainly there were swimcaps inthe early 19th century and beyond, they came in many shapes, materials and ways of wearing them. But this is a first for me to see one so similar used in the shower as part of an ad.
