Sharing a photo of himself putting on his outfit ahead of the show, he wrote: “Check the story because the boots are SICK-O-NING!” before adding the hashtag: “#GraceJones.”
Porter’s previous red carpet looks have been similarly dramatic.
He attended the 91st Academy Awards in 2019 wearing a tuxedo-gown hybrid.
The top half looked like classic men’s formalwear but the bottom blossomed out into a full velvet skirt.

At the Met Gala the same year, where the theme was camp, he wore a bejewelled gold catsuit, 10-foot wings, a headpiece and boots from Giuseppe Zanotti.
He arrived in a golden litter carried by six shirtless men and described his inspiration on Instagram at the time: “The Category Is: Old Testament Realness.”
