Parker, 50, doesn't shy away from haute couture and daring looks, and the Met Gala is the place to go big.
How did the internet react to her Philip Treacy headpiece, though? Well, she was hardly off the carpet before those watching this year's event had transformed her into a meme.
It's actually interesting to find out what different people perceive when they look at SJP's magnificently otherworldly get-up. It's like a pop culture Rorschach test.
People have suggested she reminds them of …
… a flame emoji.
… Aku, the villain of the cult cartoon series Samurai Jack.
Aku!! That's what SJP's outfit reminds me of!! Thank you internet. pic.twitter.com/a16mOx167z— Sam Lao (@THE_SamLao) May 5, 2015
… the Heat Miser from A Year Without Santa Claus.
… Aladdin villain Jafar.
… Darth Maul from Star Wars.

… Nintendo character Kirby.
… WWE wrestler Stardust.
… Mighty Morphin' Power Rangers villain Rita Repulsa.
… a representative of the Fire Nation from Avatar: the Last Airbender.

… Fantastic Four's Human Torch.
… a Dragon Ball Z character.
… and, finally, a different emoji.
Not that any of these observations would bother Parker in the least. After all, the woman who wears this headdress is absolutely fearless.
