The first Monday of May in New York is reserved for the Met Gala, but the early hours of the next day are dedicated to something even more raucous: the after-parties.
The official Gala comes with a closely followed dress code and strict rules about permitted behaviours, but the kick-ons - be they big branded bar takeovers or spontaneous and intimate gatherings - are where the high profile guests get to let their hair down, swap into less restrictive outfits and actually let loose.
This year the hotspots included Usher's Secret Garden themed do at the swanky Edition hotel in Times Square, and the FWRD & Revolve party hosted by Cardi B at nightclub Silencio.
Like the event itself, even if we didn't secure an invite, we at least get a whole new crop of standout outfits to pour over - like these.
Ayo Edebiri changing into flat boots is the mood.
Lana del Rey changed out of her frankly terrible Alexander McQueen look into an ethereal after-party outfit.
We loved Charli XCX's main look - made out of vintage T-shirts - but her after-party ensemble is also gorgeous. Both were by Marni - and her hair was done by Kiwi Matt Benns!
Zendaya's fourth outfit of the night (she changed twice on the red carpet, and again once she as inside the gala).
Queen of posing, Coco Rocha, brings tulle to the runway (sidewalk) wearing a hot pink Christian Siriano gown for Cardi B's after-party.
Model Paloma Essler one-ups Kylie Jenner's pointy bustier with her own take.
Taika Waititi changed from his brown leather Marni suit to this much more comfortable looking blue monochrome option.
Cardi B, who was hosting an after-party, changed from her dramatic black gown into a corseted red number with floral bustle.
Josh O'Connor's shiny jacket is giving NZ school ball in the early 2000s, but he pulls it off.
SZA shared an after-party snap with Lizzo, captioning it 'Cosmo n Wanda' - a reference to the cartoon characters in the series Fairly Odd Parents. They look like they're actually having fun!
Taylor Russell wore a bustier made out of wood for the main event - this dress looks much more practical for the afters.
Kylie Minogue, who attended her first Met Gala in a decade, changed into another, simpler version of her earlier Diesel dress.
Kendall Jenner kept to her archival formula, changing from her Givenchy 1999 look that had never been worn by a human to this Givenchy by Alexander McQueen ensemble, from 1997.
