These women are outraged that President Trump has taken over the White House — but not enough to miss a good party.

Hypocritical millennials who marched against the nation’s new leader in Washington on Saturday swapped out their pink “pussyhats” for beaded gowns hours later — so they could boogie down at a swank inaugural ball celebrating the 45th president.

“It feels weird because I was at the march today and I’m at the ball now, but I’m a product of my generation,” one woman, Bree, 23, said during Washingtonian magazine’s Saturday night gala. “We’re very adaptable.”

The National Institutes of Health worker said she scored her $175 ticket to the bash on Nov. 7 — a day before Trump’s surprise victory — fully expecting to celebrate the swearing-in of Hillary Clinton.

But when things didn’t turn out as planned, she carried a handmade “Future Is Female” sign through the streets of DC during the day, then headed to the party with five women pals, “because we thought this ball doesn’t take a political stance.”

Elizabeth, 24, insisted she wasn’t at the sold-out soiree to celebrate Trump, against whom she decided to march after watching a replay of his inaugural address Friday night.

“I don’t necessarily feel like I’m at a party for the inauguration,” said the personal assistant, who attended with two female friends.

“But that might be a conscious decision on my part.”

A hostess said she heard countless women discussing how they had rallied against the new president before the ball, which featured several open bars, buffet tables and dancing on three floors of the National Portrait Gallery and Smithsonian American Art Museum.

Other gals who couldn’t choose between partying and marching included former “Real Housewives of New York” star Jill Zarin.

She posted photos on Instagram showing off invites to Friday’s inauguration and a picture of herself at the insiders-only, black-tie “afterparty” in the new Trump International Hotel near the White House.

On Saturday, she also posted a shot of protesters jamming a street that leads to the US Capitol, along with the caption: “Freedom…women’s rights march..democracy at its best.”

Zarin, who’s raised money for Trump son Eric’s since-shuttered foundation, told The Post that the march wasn’t “anti-Trump,” but was “supporting women’s rights to free choice.”

“I’m looking for a middle-ground path,” she added.

“Sometimes I contradict myself and change my mind. I’m a grown-up — I have an open mind.”

A former NBC “Today” show producer said she flew from San Francisco to DC to attend the march, then decided to attend the New York State Society’s Thursday night inaugural ball when she was offered a free ticket earlier in the day.

And foreign-policy consultant Natalie Zajicova got just fours of sleep between the Moblze Foundation’s post-inauguration party — hosted by ex-boxer and Trump supporter Floyd Mayweather Jr. — and Saturday’s march.

“I think it’s more about awareness, of women’s rights,” said Zajicova, 34, who marched with several Republican friends.

“Just because you are a Republican, that doesn’t mean you don’t believe in it.”
