Sébastien Meyer and Arnaud Vaillant delivered one of this season’s fashion moments tonight. It’s almost certainly already viral. The whole process lasted about 7 minutes and took place at the end of a show that had already provided many great runways. Highlights included a dress made of thousands of embroidered glass that thundered like a thrift truck driven by an amphetamine-addled getaway driver, the designer’s Swipe bag. There was a solid gold version. All this is 1 kg and will be melted down after the show. It was created by an Italian artisan goldsmith named Gabriele Venelli and was accompanied by a sizeable guardsman.

Especially adorable was a sort of brutal metal sutured panel dress. In other works, bra cups were reinterpreted as shoulder pads. only part of it. Another spectacular touch that nicely illustrates their frame of reference was a red dress designed to mirror Fiona Johnson’s sexy glitch gown. matrix.

The collection is named Coperni Femme after the first collection in 2015. It was an ode to a reframed paradigm of femininity. The opening reference to the crinoline replaced its shrink hoops with a Trinity-inspired biker jacket draped behind her tailored jacket, alluding to the radical upgrade flavor the designer was looking for.

That final look laid it out perfectly. Bella Hadid came out in her underwear and stood on a darkened stage with her arms in front of her chest. What happened next came down to “our little geek” Meyer’s particular obsession with cutting-edge technology, Vaillant said. The scientist, who was on friendly terms with a scientist named Dr. Manel Torres, came out with a colleague and sprayed a nearly-naked Hadid from her neck to mid-calf with a white substance that looked like spray snow. The moment I put it on, it had a liquid-like luster, but it turned matte in a few minutes. Between the art and the textiles of the Métiers museum was filled with a strong synthetic odor. Hadid kept her composure during the spraydown before one of her colleagues at Meyer and Vaillant came out.

And Hadid walked down the runway in a perfectly fitted, all-white dress that until five minutes ago was liquid in a bottle — the fashion alchemy that Coperni evoked.
