It's the most fashionable night of the year, and the biggest stars in Hollywood have dressed up to the nines for the glamorous annual charity event, the Met Gala. Musicians and actors have descended on New York City for the star-studded event, which features a new theme each year. This year, attendees were asked to dress in accordance with the theme: Costume Art, and they certainly didn't disappoint.

Fashion mogul Anna Wintour was among the first stars to arrive, turning heads in a dramatic, feathered turquoise gown, which she paired with her trademark dark sunglasses. Meanwhile, Beyonce, Nicole Kidman, and Venus Williams brought their A-game as they joined the ex-Vogue chief on the infamous staircase. Let's take a look at some of the best-dressed stars to grace the red carpet.

The ex-Vogue chief was one of the first stars to grace the red carpet at the annual charity event. It's fair to say the fashion mogul turned heads in a feathered turquoise gown with a dramatic peacock-feather design and a fingertip-length cape. She accessorised the ombre dress with a statement necklace and elevated her look with a pair of strappy black heels.

No Anna Wintour look is complete without her signature black sunglasses and her perfectly styled bob as she posed up a storm for the cameras.

Tick, Tick... Boom! star Joshua Henry certainly took this year's theme in his stride as he transformed the red carpet into a dancefloor. The American actor donned a fiery red double-breasted suit with a dramatic lace trim on the lapel and a black ribbon tie. His matching suit pants brought the lace detail through the leg as he performed a dramatic dance number for the photographers watching on with adoration.

His determination and charisma shone through his unexpected performance as he showed off his best moves throughout. He was supported by a team of dancers in matching black suits, who danced in a frenzy on the famous staircase.

Sporting legend Venus Williams looked nothing short of sensational alongside her new husband, Andrea Preti, in a sparkling floor-length gown. Her sensational black dress hugged her hourglass curves with a dramatic train at the back. She accessorised her look with a pair of strappy heels and a dramatic silver collar necklace, which complemented the diamond gems scattered through her intricate updo.

The tennis ace added a full face of makeup that celebrated her youthful glow as she beamed alongside her doting husband. Preti complimented his new wife in a sleek black suit, paired with an oversized burgundy bow tie and matching pocket square.

Aussie babe Nicole Kidman sent temperatures soaring as she stepped out in a red sequined dress for the star-studded event of the year. The blonde bombshell stood out against the sea of black-clad photographers as her feathered dress gently blew in the breeze.

She straightened her hip-length hair as she posed up a storm on the red carpet and schmoozed with the stars in the reception room. The 58-year-old actress proved that age is just a number, her youthful glow lighting up the room in her vibrant red number.

New bride Lauren Sánchez Bezos turned up in a classic little black dress that hugged her every curve. The brunette beauty, 56, looked nothing short of sensational in the busty black dress. Her dress featured dramatic diamond-encrusted straps that complemented her golden tan as she posed up a storm on the famous staircase.

She opted for traditional glam makeup and styled her chocolate tresses into a loose, bouncy blowout as she worked her best angles for the photographers. However, the starlet has faced backlash over her attendance after her husband Jeff Bezos, 62, sponsored the event, giving a rumoured $10million to the Costume Institute in exchange for being named honorary co-chairs.
