Au revoir Paris! The final leg of the Fashion Week four-city marathon concluded on Tuesday in an out-of-this-world fashion. Just hours after Karl Lagerfeld transformed Paris’s Le Grand Palais into a fantasy beach for Chanel’s SS19 showcase, Nicolas Ghesquière sent models down the Louis Vuitton runway wearing an array of rocket-ready looks paired with flying saucer-shaped accessories. Similarly, PFW started off with an equally spectacular bang, courtesy of a kitschy showcase from Gucci, who decamped from Milan to present its Spring 2019 collection. Next up was Dior, where a troupe of dancers took over the runway as models showed off the maison’s latest collection. The preceding show from Jacquemus was equally as memorable (Cue: the oversized straw bags). Click through the slides in the gallery ahead for the key looks you absolutely must see from Paris Fashion Week SS19 — including Miu Miu, Alexander McQueen, Balmain, Sonia Rykiel, and more.
