I don't know my history, but I would guess these #femmefatales really came into prominence with the early days of Hollywood whcih featured Vamps and Ziegfeld girls. Over time it yielded to burlesque, circus shows and even Spectacles on Ice. Playboy Bunnies put them on full display during the 60's.
This post is a draft saved almost 3 years back that was just waiting for the time to present itself to me. It was from a photo collage that showed the backstage antics of the traveling Side Show. There is something gritty to me about the congruence of pump heels in muddy fields of tents & train cars. They brought the glamour to the masses is rural areas that must have seen it as decadent. Whereas some of the 40's pin-up types seemed manufactured, there is something that appears to me to be genuine in these #carny girls. Maybe it is the photos with candid access, but I still prefer this to what many would now call Camp as depicted at this year's Met Gala. Give them a look and click on the link for the full album.
