And still stylish:
This is generally believed to be a 1956 advertisement. (The fact that it’s on page 56 is presumably a coincidence.) Archer Mills had merged with Wayne Knitting Mills (which in turn was owned by Munsingwear) back in 1940. And Vanity Fair was shut down and incorporated into Vogue in 1936, only to be spun off again in 1983.
About 2007, I flipped this and used it for a CD cover.
