So much derp in this thread it's hard to know where to begin.
The theme of the event wasn't The Hunger Games, it was In America: A Lexicon of Fashion. I guess the overarching idea was some kind of fantasy thing, but it was left to the individual attendees on how far they wanted to push it. Lots of them just came in black tie and ball gowns.
Musk's girlfriend is a big sci-fi fan, and her costume was supposed to be a Dune homage. I'm sure that will outrage the many Frank Herbert fans here, but that was her thematic inspiration.
The sword is NOT a real weapon, (well, maybe aside from the pointy bit, as the Chief Revenue Officer(?) acknowledges)...it comes from the studio of a
art collective who transform gun parts into "art". They're just about as edgy as one might expect.
"The sword has more of a story behind it than most accessories. It was made by MSCHF, the Brooklyn-based art collective who made headlines earlier this year with "Satan Shoes"—the notorious sneaker collaboration with rapper/singer Lil Nas X that featured a bronze pentagram and an inverted cross containing a drop of actual human blood."
"Turning a gun into a sword is side-cycling, where the output is just as desirable, but no longer deleterious to society," MSCHF Chief Revenue Officer Daniel Greenberg told Newsweek via email. He added that "by turning guns into swords we are essentially preserving the symbolism of the object but making it significantly less deadly (and way more rad)."
BTW, they're getting sued by Nike for the "Satan Shoes".
