This year, the annual Met Gala took place on May 6, the first night of Ramadan.
And one celebrity on the red carpet made a sartorial nod to the start of the holy month, by donning traditional dress for the occasion.
Rapper French Montana, who was born Karim Kharbouch in Morocco, wore a soft pink thobe and a metallic printed agal to the fashion event, held in New York's Metropolitan Museum of Art.
The Unforgettable star, 34, revealed during a brief interview with fashion website Just Jared that his look — plucked from Gucci's Dapper Dan collection — was designed to honour the first night of Ramadan.
The Rabat-born musician shared an image of his ensemble on his Instagram account, wishing his 11.4 million followers "Ramadan Mubarak". The star also dubbed himself "Sheikh Montana".
The star, who moved to the US as a teen with his family, has previously spoken about his pride in his heritage.
“I am still an Aroubi," he said at a press conference in Morocco last year.
Montana was joined by another famous face from the region on the night — Rami Malek.
The Oscar-winning actor stepped out at the Met Gala, where he posed with actress and singer Charlotte Gainsbourg on the red carpet.
The Bohemian Rhapsody star wore a custom outfit from Saint Laurent for the fashion bash, with metallic striped shoes and a glimmering gunmetal shirt adding a flamboyant touch to proceedings.
The theme for the 2019 Met Gala was Camp: Notes on Fashion, based on Susan Sontag’s seminal 1964 essay of the same name.
The event, the first of which was held in 1948, raises funds for the New York museum's Costume Institute, which is currently hosting an exhibit also based on Sontag's work.
