@lain reminded me that catherine the great used to hold crossdressing balls regularly.> Empresses Elizaveta Petrovna and Catherine the Great sometimes allowed themselves a little mischef and organized events to which the public should show up dressed as opposite sex. These masquerades were held regularly, and during fall-winter of 1744 they were held every tuesday in Moscow. Empress Elizabeth complied the guest list herself and imposed a strict ban on showing up in "own" costumes. Ladies only dressed as gentlemen, gentlemen only dressed as ladies. No exceptions. Catherine forced guests to change to dresses of opposite sex, and even buy them on credit. Right during the ball.translated from: https://www.sobaka.ru/fashion/heroes/67114
