This might sound just a little bit geeky, but I kind of love how an entire decade can be summed up in a single dress. People express the way they see themselves and want to be seen by others in their clothing. Then, retrospectively, all the clothes of a time period get whittled down into a single iconic garment.
OK, make that two dresses for the seventies, which was a decade with a dual personality.
Classic flapper fashion: dropped waist, youthful, iconoclastic
1930’s: influenced by Hollywood and very body conscious
1940’s: power shoulders, peplum waist, tropical
1950’s “Fit and Flare”: slim waist, full skirt, ultra feminine
1960’s, like the 20’s: boundary-breaking, young, with an undefined waist, but in eye popping colors and patterns
1970’s dress, take 1: Bohemian, hippie, Ethnic, exotic, prairie
1970’s, take 2: the wrap dress, a perfect career woman uniform
1980’s dress: bold, excessive, over the top, and those shoulders
