Sienna Miller, 42, brings back boho in a plunging lace blouse and bootcut denim jeans as she departs Met Gala afterparty with boyfriend Oli Green, 27

Sienna Miller was boho chic as she attended a star-studded Met Gala after-party with boyfriend Oli Green in New York City on Tuesday.

The actress, 42, was spotted leaving the boozy bash in the early hours of the morning with her beloved boyfriend Oli, 27.

Hours after standing on the iconic Met Gala steps in a glamorous lace dress, Sienna changed into a casual attire with chunky brown wedges.

The mother of two, who welcomed her second child with Oli just four months ago, donned a low-cut blouse paired with bootcut denim jeans.

Meanwhile, Oli looked incredibly handsome in a smart navy blue tuxedo and crisp white shirt, accessorized with black Adidas sneakers.

Earlier in the evening, Sienna stunned in a flowing white lace dress as she graced the 2024 Met Gala carpet.

The actress turned heads when she arrived at the star-studded gala in an incredibly chic ensemble.

Sienna arrived hand-in-hand alongside Greta Gerwig, Chemena Kamali, Emma Mackey and Zoe Saldana.

Stars in attendance on the night included Kim Kardashian, who sent shockwaves as she flaunted her astonishingly tiny waist in a custom-made silver Maison Margiela dress by John Galliano.

Her sister Kylie Jenner kept it simple and chic in a rosewater-colored strapless dress by Oscar de la Renta, paired with a rose in her hair.

Jennifer Lopez posed up a storm on the steps in a dazzling, sparkling, sheer, bejeweled ensemble.

Fellow co-chair Zendaya made a statement in a blue and green custom Maison Margiela by John Galliano dress, with branch and fruit accents.

Zendaya wore a second look for the Met Gala – a black Givenchy by John Galliano dress from 1996 – with a floral hat from Alexander McQueen from 2007.

The Costume Institute’s Spring Exhibition falls on the first Monday in May each year and is held at the Metropolitan Museum of Art in New York City.

This year the event was called Sleeping Beauties: Reawakening Fashion, while the dress code was The Garden of Time.

Jennifer Lopez, Zendaya, Bad Bunny and Chris Hemsworth served as this year’s co-chairs. Vogue’s is also on the committee Anna Wintour.

The chairs of honor for the evening were Loewe creative director Jonathan Anderson and TikTok CEO Shou Zi Chew.

“This year’s co-chairs reflect a variety of career achievements and each has their own style history at the Met Gala,” Vogue said.

The display case contains approximately 250 items from The Costume Institute’s permanent collection, many of which are too fragile to ever be worn again.

The pieces are all rendered using elements such as AI, GCI and more, while themes such as land, sea and sky are played out.
