Ivanka Trump, 36, is the eldest daughter of President Donald Trump, 72.
She is employed as a senior advisor to her father, as is her husband Jared Kushner, 37.
The mother-of-three lives in Washington DC, close to his husband and his wife Melania Trump, 48.
However, it appears the politician has made a fashion faux pas concerning Melania.
Ivanka Trump wore a £2,432 suit made by a designer who has refused to dress Melania.
The designer in question has also been vocal in criticising Donald Trump’s policies.
Gabriela Hearst said, about Melania Trump in 2017: "If they want to wear the clothes, they can buy the clothes.”
It was Twitter user Kate Bennett, a reporter at the White House, to first revealed the fashion faux pas.
She tweeted: “@IvankaTrump is wearing this @gabrielahearst suit.
“Hearst is a vocal critic of Trump administration policies.
“Her 2017 collection was actually inspired by female Democrat Senators, including @KamalaHarris @SenDuckworth.”
Gabriela Hearst is known for her suiting and this off the shoulder pantsuit.
The straight leg cropped trouser Masto pants cost £781.81.
Matching, the Dorothea blazer costs £1,650.05.
Speaking about her collection inspired by Democrat women, Gabriela told Yahoo! in 2017: “Before, we were thinking about dressing Hillary, and now it's like, how do we bring Donald Trump down?
“Women that put their strength and their qualities in the service of others seemed like a good reference to keep us motivated.”
A number of fashion designers have been critical of the Trump administration, and refuse to dress the First Lady.
In January 2017 Donald Trump made comments at the the Leadership Luncheon held at Trump International Hotel in Washington.
Trump reportedly said: “Tom Ford came out and said he was not dressing Melania.
“He was never asked. I never liked him or his designs. He’s never had something to dress like that [pointing to his wife, who was in the room at the time].”
Despite the fact the US designer has previously made a custom gown for Michelle Obama, he said his clothes are “too expensive” for Mrs Trump to wear.
Ivanka Trump: Five facts about Donald Trump’s daughter
Ivanka is not, in fact, her real name. She actually shares her mother’s name Ivana.
Explaining why she is known as Ivanka in a 2010 tweet, she said: “In Czech, Ivanka is the baby name for Ivana, like Bobby is to Robert.”
Ivanka was well known to the American public before her father became President thanks to appearances on TV.
She made short cameos on Project Runway and Gossip Girl, as well as becoming a primary boardroom member on The Apprentice with Donald.
Ivanka married Jared Kushner on 25 October 2009 at Trump National Golf Club in Bedminster, New Jersey, after a three month engagement.
Barron Trump served as ring bearer, as Ivanka wore a custom Vera Wang gown accessorised with diamonds from her fine jewellery collection.
Ivanka was raised as a Presbyterian Christian, but converted to Judaism to allow her to marry Jared Kushner.
Ivanka studied with Elie Weinstock from the Modern Orthodox Ramaz School, on the Upper East Side of Manhattan in New York City.
She now keeps kosher and observes the Jewish Sabbath. Ivanka said in the February 2015 edition of Vogue: "We're pretty observant... It's been such a great life decision for me... I really find that with Judaism, it creates an amazing blueprint for family connectivity.
“From Friday to Saturday we don't do anything but hang out with one another. We don't make phone calls."
Ivanka ran a fashion line for 11 years, only recently closing it down. She also had a fine jewellery store which closed in March 2017.
Ivanka now focuses on her role as an advisor to the President, Donald Trump.
