When did girls start wearing pink?

I read this article today about when pink came about as THE color for girls. Not until the mid 1980's. That's so weird, I just assumed pink has always been a girl color. Not so!

"In June 1918, an article from the trade publication Earnshaw's Infants' Department advised, "The generally accepted rule is pink for the boys, and blue for the girls. The reason is that pink, being a more decided and stronger color, is more suitable for the boy, while blue, which is more delicate and dainty, is prettier for the girl." Through the following decades, several department stores, including Filene's, Halle's and Marshall Field, recommended that boys be dressed in pink.

Maglaty describes the turning point as the women's liberation movement in the mid-1960s. Young women gravitated toward gender neutral clothing to rebel against the subservient role of women dictated by society. But by the mid-1980s, gendered clothing returned in a big way. Jo B. Paoletti, historian and author of the forthcoming Pink and Blue: Telling the Girls From the Boys in America, remembers this clear distinction, as it was between the births of her two children, one in 1982 and another in 1986: "All of a sudden it wasn’t just a blue overall; it was a blue overall with a teddy bear holding a football." Perhaps the biggest factor in cultivating a gender obsessed society is the rise of consumerism among young children. Now, as early as age 3, children are subject to marketing campaigns that reinforce the notion that "what makes someone female is having long hair and a dress," says Paoletti."
