This advertisement for Vanity Fair Silk Underwear is from 1921.
The roots of Vanity Fair date back to 1899 and the founding of the Reading Glove and Mitten Manufacturing Company. In 1919 the company added undergarments to the product mix and took the name Vanity Fair Silk Mills. The company then went public in 1951, and in 1969 acquired its first jeans company, H.D. Lee Company, and also changed its name to VF Corporation. The addition of Blue Bell was important because its doubled the company's size and provided VF with a 25 percent market share in the $6 billion jeans industry. Moreover, VF achieved a level of diversification by adding the likes of Red Nap workwear, Jantzen swimwear, and JanSport backpacks.
And finally some illustrations showing the 'Double Back Knicker', 'Sure Lap Union Suit' and the 'Envelope Chemise'.
