Tom and Lorenzo have made the point recently in one of their
Mad Style posts (which specifically dissect Mad Men's clothing choices and how they serve the story) that:
"It was a quirk of mid- late 1960s women’s styles - and you could have a field day postulating as to why; many others already have - that they were largely infantilized; like this schoolgirl dress, sporting naive detailing like bold sash details and big buttons. She could add some brightly colored hosiery and a pair of Mary Janes and be wearing something perfectly fashionable for an 8-year-old and a 25-year-old at the same time."
I was flipping through some of my images from a 1966 Spiegel catalog, and boy, ain't that the truth.
