The conversation around blackface often involves clueless or racist (or incredibly both?) white people who paint their faces black like Al Jolson in "The Jazz Singer", and proceed to put on an incredibly offensive and garbage costume. The purposes of the costume is never to trick anyone into thinking you're black, or to try to appropriate looks to try to look more beautiful. That's what makes the "Blackface Thots" trend so strange -- it shows white women absolutely going all out to try to look like beautiful black women for the purposes of Instagram. And the examples of this are beyond plentiful.
