Whether you love or loathe the Louis Vuitton x Jeff Koons collaboration that debuted yesterday, you've got to hand it to designer Nicolas Ghesquière — this is the second very buzzy collab he's pulled off this year. To celebrate the accomplishment, Ghesquière invited a bevy of celebrity guests to come celebrate with him by eating a fancy dinner in the Louvre right under the watchful eye of the Mona Lisa herself.
It was a major flex on the part of the brand, and the celebs in attendance — which included actors, influencers and models — used the occasion to show off some outfit flexes of their own. Cate Blanchett showed up in a trousers-and-belted top combo that might just convince us to give cargo pants a second chance, while bloggers like Chiara Ferragni and Aimee Song sported more straightforward dresses paired with clutches from the new collaboration. Pointy-toed boots and lots of black were recurring themes in attendees' outfits, but celebs like Chloë Sevigny and Michelle Williams lightened things up with a color-blocked sweater and pink slip dress, respectively.
