To me that's long hair (albeit on the shorter side--but not short).
When I say short hair, I mean SHORT--like Mia Farrow after she cut-off her long hair while starring in Peyton Place.
And when I say traditional, I mean like 1900 not 1950--those chemical hairdo's of the 1950's and, worse, early 1960's are grotesque.
I'd argue that the 60's and 70's brought back long hair. In fact, many claimed long hair was revolutionary and freeing. Heck, I know plenty of older babyboomer/ex-hippie generation women who still wear long hair. It may be grey but it's long. I'd say they are the antithesis of your traditional woman/long hair thesis.
They wore their long hair wildly. See my post number 118. Long/short in context. Everything in context.
