Writing gushy hyperbole-strewn love letters to friends you don't want to have sex with. Of course now popular media and some historians are looking at those through the lens of today's mores to insist that they did always want to have sex with the people they sent those flowery, purplely-prosey love letters to.
On a less serious note, from the mid-nineties' rap videos, wearing a windbreaker/tracksuit and goggles for absolutely no reason. It amuses me to this day that it ever caught on.
I think I'd like to try a Regency era riding coat and breeches with tracksuit stripes up the side AND pointless goggles atop a powdered wig... and some Doc Marten slip-ons!
Of course that was, to my knowledge, never the fashion anywhere but it should have been. :(
