It was common now to extend the natural border of your mouth with liner, making a girls look more feminine and – well – voluptuous ! Pinks and Reds were the common mix. Orange-red lipsticks for blonde hair, redheads and other medium dark colors; and purple-red lipsticks for dark haired . A survey in 1951 found that more than two thirds of women now regularly wore lipstick. As a result – long lasting lipstick was the next goal, and the first kiss-proof stay-on lipstick was introduced by a lady called Hazel Bishop in 1950. “It stays on YOU,” declared the ads for Hazel Bishop’s smudge-proof lipstick, “… not on Him!” It was so successful that she formed Hazel Bishop Inc the next year. Sales of her lipsticks increased from $49,527 in 1950 to $10,100,682 in 1953 !
