She paired the haute couture creation with sky-high platform shoes and a clutch in matching tones.

Lopez’s necklace, with nearly 100 carats of diamonds, was provided by Tiffany & Co., as were her earrings, bracelet and two rings.

Lopez is a co-chair of this year’s esteemed event, alongside Bad Bunny, Chris Hemsworth, Zendaya and, of course, Vogue’s Anna Wintour.

Guests at the gala will be able to preview the Costume Institute’s exhibition, “Sleeping Beauties: Reawakening Fashion.” The dress code for Monday’s event was “The Garden of Time,” based on a 1962 short story by J.G. Ballard.

When Vogue first announced the theme for this year’s gala, it described the dress code and accompanying exhibition as centering on “fleeting beauty.”

“The most obvious interpretation would be to embrace the ‘garden’ part of ‘The Garden of Time,’” the fashion bible said, instructing guests and followers alike to “Think melancholic florals (as moody florals aren’t moody enough).”

Wintour said in an interview with the “Today” show on Monday that the exhibition actually broke her “cardinal rule.”

“When we came up with the title ‘Sleeping Beauties,’ it’s wonderful and poetic and romantic, but actually, it could be many, many things,” she explained.

Wintour said that she imagined “we’ll see a lot of flowers” on tonight’s red carpet.
