Liquid Plastic Termed Likely Hose of Future MINNEAPOLIS. A Minneapolis beauty expert predicts that in the near future women may buy their stodkings "by the gallon." Myndall Cain, a beautician who has devoted many hours to worrying worry-ing about the possible shortage of silk stockings, believes a plastic substance that can be painted on the legs may be just what every woman needs. "It could be applied with a sponge and removed with a special oil wash," she explains. "It would last for two or threi days and probably would cost aboul 50 cents an application." Until the day of the plastic "stocking" "stock-ing" arrives Miss Cain suggests that women can meet any hosiery short-age short-age by painting the legs with cosmetics, cos-metics, by wearing knee-length bootees, "which were stylish when grandmother was a girl," or by wearing cotton, wool, knitted, crocheted cro-cheted or net stockings.
