The first Monday in May was as spectacular as ever. Stars from the worlds of fashion, music, film and sport stepped out on to the red (well, pink) carpet at New York's Metropolitan Museum of Art for the year's most stylish event. The annual Met Gala took place on Monday, with the of "Camp: Notes on Fashion". <strong>Scroll through the gallery above to see all the best looks from this year's Met Gala.</strong> (The dress code is typically informed by the opening of the venue's annual fashion exhibition, which this year is centred on Susan Sontag's seminal 1964 essay <em>Notes on 'Camp'</em>). Stars such as Cardi B and Jennifer Lopez donned their theatrical best for the gala, joined by this year's co-chairs Lady Gaga, Harry Styles, Serena Williams and Gucci’s creative director Alessandro Michele. The night typically produces several moments that go down in fashion history. This year's contenders included Lady Gaga, who made a number of outfit changes on the red carpet, Katy Perry, who came dressed as a human chandelier, and Jared Leto, who carried a model of his own head as an accessory. The Met Gala, which was first held in 1948, raises funds for the New York museum's Costume Institute, with tickets becoming a coveted item for A-list celebrities. Since 1995, <em>Vogue</em>'s editor-in-chief Anna Wintour has been chairwoman of the gala and reportedly has the final say on the guest list. She has been known to stop people from attending – and it's not only people who are banned. There are strict rules once you do make it inside the museum, including no selfies (although many celebrities have broken this rule) and no social media posting.
