Blake Lively’s Met Gala Dress Had A Surprise That Made The Crowd Roar

If anyone knows how to steal the show, it’s Blake Lively.

Lively, who’s co-chair of this year’s Met Gala alongside her husband Ryan Reynolds, ignited the red carpet with her arrival on Monday evening.

Donning a copper Atelier Versace gown, Lively and her assistants performed an unexpected switch-a-roo right in the middle of the carpet.

Her bow-embellished dress metamorphosed into an aqua blue showstopper as her assistants helped ‘unwrap’ it on the red carpet.

“I arrived copper and then, like New York City classic architecture, I patinaed,” the actor said of her unveiling.

Resembling iconic New York City landmarks like the Empire State Building, the dress was accessorized with a crown featuring seven spikes in a nod to the Statue of Liberty.

The “Gossip Girl” star said this year’s event was “especially nerve-wracking.” “Being one of the hosts, you really feel like you need to bring your A-game,” she said.

This year’s Met Gala theme was “In America: An Anthology of Fashion,” but Lively put her own twist on it by representing New York and focusing on the “architecture rather than just the fashion.”

Lively has dominated the Met Gala red carpet over the years, and she has yet to disappoint.

At the 2018 Gala, themed “Heavenly Bodies: Fashion and the Catholic Imagination,” the actor sported a crimson Versace gown with an embroidered bodice, an extra-long train and lots of bejeweled action. The entire ensemble took 600 hours to make by hand.
