Ella Emhoff wows crowd in ‘best dress at DNC’ by Joe Ando-Hirsh

She saved the best for last.

Brooklynite Ella Emhoff wowed the crowd on the final night of the Democratic National Convention in Chicago, taking the podium in a powder blue and white couture dress to sing the praises of her stepmom — Kamala Harris.

The speech was heartfelt, but Emhoff’s ethereal off-the-shoulder number — which featured a pastel blue, drop waisted bodice and a white skirt with a mid-calf hemline — wound up stealing the show.

Unlike the Democratic nominee, who kept it safe with pantsuits by Chloé, Emhoff’s one-of-a-kind gown, lauded as the “best dress at the DNC” by one critic, turned out to be the handiwork of work of an up-and-coming TikTokker — also living in the Big Apple.

Joe Ando-Hirsh, who graduated the Fashion Institute of Technology in 2020, collaborated with Emhoff on the show-stopping frock, telling The Post it was “an amazing experience.”

“When I saw her come onto the stage I let out a huge sigh of relief!” Ando-Hirsh said. “I thought she looked amazing and really pulled the entire look together.”

Ando-Hirsh teased his buzzy client on social media in the days leading up to the big reveal, suggesting that this one might be his favorite thus far — despite previously creating garments for stars like Dakota Johnson, Maitreyi Ramakrishnan, Millie Bobby Brown and Rachel Zegler.

“I’ve made dresses for so many different events and people, but this one felt so personal and I really wanted to help Ella have her moment in an elegant way,” he said.

Emhoff, daughter of Second Gentleman Doug Emhoff, who has been called “The First Daughter of Bushwick,” has become something of a Gen Z fashion icon — in part due to her eclectic personal style and involvement in the fashion industry as a model, artist and avid knitter.

The 25-year-old attracted the attention of viewers throughout the week with her various and varied looks — but nothing like this.

And while she’s previously worn the work of acclaimed fashion houses like Helmut Lang and Thom Browne, Emhoff reached out to Ando-Hirsh ahead of the DNC to create a custom piece, collaborating on “an elegant, tea party-themed look” but made “more modern and elevated,” the designer said.

“I really wanted Ella to stand out in a very distinguished way,” said Ando-Hirsh, who met Emhoff through a mutual friend.

On TikTok, viewers raved about the fab frock.

“I could not take my eyes off her dress!! She looked stunning!! She’s a free spirit and the dress shows that!! Good job,” said one armchair critic.

“Omg I was wondering who designed it and you pop up on my FYP! You did amazing, sweetie!” cheered another.
