British actor Benedict Cumberbatch, known for “Sherlock” and “Doctor Strange,” proudly wore an all-vegan suit made with bamboo and “peace silk” at this year’s Met Gala.

Cumberbatch, who went vegan last year, attended this year’s Met Gala, an annual fundraising event for the benefit of the Metropolitan Museum of Art’s Costume Institute in New York.

According to Daily Mail, Cumberbatch became one of the centers of attention as he arrived at the fundraising event with his wife, director Sophie Hunter.

“We spent ages talking about it and planning it for about three weeks before he flew to the U.S,” Joe Woolfe, Cumberbatch’s stylist for 10 years, told Daily Mail.

“He’s vegan, so that meant there were a lot of fabrics we couldn’t use. We ended up using an amazing English bamboo fabric from Huddersfield Fine Worsteds.”

Woolfe added that he acquired Cumberbatch’s shirt from designer Emma Willis, who dresses Prince Charles, and made sure that the silk would meet the vegan actor’s standards.

“It was silk, but peace silk, which doesn’t involve killing the worms, so it’s fully vegan and cruelty-free,” he said.

“I had to get a few for him to choose from, because I know what he’s like, and if I just give him one thing he’ll feel like he’s being cornered. But he always ends up choosing what I offered first!”

Aside from Cumberbatch, vegan musician Miley Cyrus and her husband Liam Hemsworth both made sure to stay cruelty-free at the Met Gala.

The vegan couple both showed off cruelty-free Yves Saint Laurent outfits and footwear, created by designer Anthony Vaccarello, for the annual fundraising event’s “Camp: Notes on Fashion” theme.

Sharing photos of her and Hemsworth at the gala to her 92.5 million Instagram followers, Cyrus said: “Thank you @ysl @anthonyvaccarello for the custom vegan faux leather platforms! (Liam’s shoes are also vegan!)”

However, some celebrities followed the fundraising event’s exaggerated fashion theme by wearing an exaggerated amount of feathers.

Animal rights organization People for the Ethical Treatment of Animals (PETA) called out celebrities such as Cardi BKendall JennerKylie Jenner, and Naomi Campbell for supporting animal cruelty.

“With all those privileged folks in attendance, you’d think the Met Gala could afford a little compassion for one night,” PETA said in a statement.

“This year’s event kept up with its usual extravagant fashions and runway shenanigans — but to [our] disappointment, it featured a LOT of feathers. (We’re looking at you, Jenners.)”

“The fashion world now knows how cruel it is to wear dead animals’ fur, but as far as we can tell — with everyone trying to look like Big Bird at the gala — it’s still ignorant about where feathers for those gaudy outfits come from.”

“Those feathers once belonged to living, feeling animals and were ripped out of their bodies, which were left bloody, broken, and destroyed,” PETA concluded.
