It's one of fashion's most outrageous and outlandish nights, when stars and designers are given a carte blanche to do their wildest in the wardrobe departments.
So, naturally, the annual Met Gala witnesses some of the most memorable – and meme-able – style moments of all time.
This year's red-carpet event, held at New York's Metropolitan Museum of Art on May 6, was no exception, with celebrities such as Lady Gaga, Katy Perry and Janelle Monae going all out.
The theme for last night's gala was Camp: Notes on Fashion, based on Susan Sontag's seminal 1964 essay of the same name – the work is also the basis for the museum's 2019 fashion exhibition.
The dress code, understandably, paved the way for some OTT outfits, which in turn spawned some of Twitter and Instagram's funniest memes to date.
Below, we round up the best of the bunch.
Lady Gaga inspired thousands of reactions, thanks to her multiple on-the-red-carpet costume changes:
