Grimes took a sword repurposed from an automatic weapon to the Met Gala

She told Vogue: “It’s not a prop sword, I tried to pick it up and this is not really a one-handed situation.

“The sword is based on a western European sword from the end of the Middle Ages around 1400 ... [It] is a permanent piece of the Met’s collection, and the sword is also cast from a Colt AR-15A3...

“It’s from these people who are getting people’s [guns] who don’t want to have their automatic rifles anymore, and are melting them down and making them perfect replicas of medieval swords, which I think is just so cool—I think it’s a beautiful thing."

Grimes was delighted to work with the designer because she loves the way she pushes boundaries with her work.

She said: "“Iris has been one of our favourites. I just feel a kinship to women behind the computer. She is a technologist, you know? And I feel like she’s always been on another level.

"Like, to me she’s kind of got an argument for being the current era McQueen or something, she’s pushing the boundaries in a way that I don’t know if anyone is actually competing with her?

"We had offers to go with bigger people, but… the first thing she sent through, we were like, this is f****** fire.”

Grimes' entire look was based on 'Dune', Frank Herbert's novel which was adapted for the big screen by David Lynch in 1984 and has been remade by Denis Villeneuve, whose adaptation will be released next month.

She explained: "“We were working with the Dune movie people. [They were going to] hire me as a professional fan, or like, an influencer or something.”

However, no contracts arrived in time to make the collaboration official.
