Girls Are Taught To 'Think Pink,' But That Wasn't Always So [View all]

Before Gatsby, a 1918 trade catalog for children's clothing recommended blue for girls. The reasoning at the time was that it's a "much more delicate and dainty tone," Finamore says. Pink was recommended for boys "because it's a stronger and more passionate color, and because it's actually derived from red."
To our 21st century ears, all this men in pink stuff may sound a bit blushy. "It's so deeply entrenched in us and our culture," says Finamore. "We think of pink as such a girlish color, but it's really a post-World War II phenomenon."
When the war ended and the men came home, Rosie the Riveter traded in her factory blues for June Cleaver's pink apron. In the postwar ideal, men reclaimed the workplace, and women stayed home with babies and shiny appliances. Femininity got wrapped in pink, and so did products from shampoos to fancy fashion.
In 1947, after the shortages and rationing, and straight skirts of war, Christian Dior introduced the New Look. "It is this overtly feminine silhouette," Finamore explains. "You have soft shoulders, a bust line, a wasp waist and voluminous skirts."
