The article says her dress was wet. How the hell did she wet her top in the middle of a swanky bullshit event? Did she come that way? Or was the wetness just an illusion? (She is wearing a towel-dress in the outdoor pictures.)
I’m not sure what she had on beneath that dress, but judging by the fact that she kept her hand in front of her crotch, the answer may be “nothing.”
Sample:

She went full Giuliani with the streaks down her face, although her streaks were intentional. Maybe it was an homage to Rudy, given his immense popularity with Black females.

Maybe she saw another woman wearing the exact same dress and thought, well, time to improvise.
