I love to see people wearing vintage clothes (prefer sixties and seventies) including fifties clothes if they look like the kind of clothes people ordinarily wore in the fifties. Like a Fair Isle tank top and a librarian style skirt - that would be fifties.
But an enormous petticoat with garish dress, tattoos, victory rolls and a load of eyeliner makes me fear the wearer is going to burst into a burlesque routine at any moment.
My mum complains about how ridiculous, ugly and impractical such clothes were in the fifties. They should have died a death then. I'm sure there are also Victorian fashions worth bringing back that aren't corsets.
And if it is a choice between quirky fifties and steampunk, then quirky fifties is slightly less awful.
