Monday was girls' night for Sienna Miller!

The Horizon: An American Saga actress attended the 2024 Met Gala on May 6, posing alongside fellow Chloé-clad celebs Zoe Saldaña, Emma Mackey, Greta Gerwig and Chemena Kamali.

All five women were dressed in looks inspired by this year's dress code, "The Garden of Time." The clothing criteria falls in line with the "Sleeping Beauties: Reawakening Fashion" theme.

For Miller's ensemble, the 42-year-old actress opted for a '70s-era high-low lacy frock, featuring a high neckline, tiered sleeves and mini front hem.

Wearing her blonde locks down in a middle-parted, wavy style, Miller finished the ethereal look in studded black cuff-style shoes.

The Wander Darkly actress has attended the Met Gala a whopping nine times, making this her 10th.

She attended her first in 2006, the year she was one of the co-chairs alongside Burberry's Christopher Bailey for the "AngloMania: Tradition and Transgression in British Fashion" theme.

Since the gold sequin minidress she wore back then, Miller has pushed the boundaries with her daring style. She even rocked bleached brows and a furry Gucci ensemble in 2023 in honor of the "Karl Lagerfeld: A Line of Beauty" dress code — presumably inspired by the late designer's cat, Choupette.

The night before the Met Gala, Miller and boyfriend Oli Green, who've been dating for more than two years — were spotted having a rare night out in New York City, attending Anna Wintour's famous pre-Met Gala dinner.

The new parents, who welcomed a baby girl seemingly in late 2023, were all smiles and clad in chic outfits for the festivities, leading to speculations about their attendance at fashion's biggest night, though the actress appeared to attend without Green, 27.

Miller and Green have been dating since 2022. The pair went public with their romance when they were seen leaving the 2022 BAFTA Film Awards together and later made their red-carpet debut at Vanity Fair's Oscar party in March of that year.

While speaking with Vogue in December 2023, Miller admitted she'd "imagine" that the couple's 14-year age gap "would be complicated for anyone to get their head around, but there’s been nothing but love and joy."

Aside from Miller's daughter with Green, she also shares her older daughter Marlowe, 11, with ex-boyfriend Tom Sturridge.
