Rich NY liberal brags about fighting climate change by wearing old expensive clothes and taking the subway

New York City socialite and Hollywood pseudo-celebrity Nicky Hilton Rothschild — yes, that Hilton, and yes, that Rothschild — says that she's repurposing old designer outfits and riding the subway in order to do her part to fight climate change.

What are the details?

During Fashion Group International's Rising Star Awards, Rothschild said that she has a high-brow approach of combating climate change, which includes wearing old clothes and taking public transportation.

"I am here in support of [sustainable fashion brand] Maison de Mode ... so I pulled out an old Alice + Olivia skirt and wore a vintage Chanel bag, and I took the subway here," she said during the awards ceremony, which was held Wednesday at Cipriani 42nd Street in New York City.

"I took the 6," she gushed. "I feel like I am doing my part."

Rothschild does have high-brow taste: At the time of this writing, Alice + Olivia skirts range in retail price from $225 to $1,795.

Her wedding, which took place in 2015, featured a Valentino-designed dress that cost $77,000 — one of the most expensive wedding dresses in documented history.

Anything else?

Climate philanthropy apparently runs in the Hilton girls' blood: Sister Paris famously addressed climate change in just seven words in 2017.

"This is earth. It's hot. Don't pollute," she shared in a viral tweet to her 17 million Twitter followers.

Paris also once campaigned with Soda Stream for an advertisement designed as a spoof on environmentalism, so there's that, too.

The video, titled, "Paris Hilton just changed science forever," is an advertisement for Soda Stream, a manufacturer of at-home brewed sodas and sparkling waters.

At the end of the ad, she quips, "And you can make it in the comfort of each one of your homes. Soda Stream: because planet earth is so cute."
