All the hidden details of Jill Biden's Inauguration Concert outfit

• Jill Biden's Inauguration Concert outfit had a number of hidden symbols.
• The first lady wore a custom ivory coat and matching embroidered dress by Gabriela Hearst.
• Her dress was adorned with flowers for every US state and territory.

Vice President Kamala Harris' inauguration outfit was packed with hidden meanings, but she wasn't the only one who made a powerful fashion statement on Wednesday.

First lady Jill Biden wore multiple symbolic looks throughout the day, including an ocean-blue dress and matching coat from the NYC-based luxury fashion label Markarian.

A representative for Markarian told Insider that the shade of blue worn by the first lady was chosen to "signify trust, confidence, and stability."

Later in the evening, the first lady took part in the "Celebrating America" special wearing an outfit that was also filled with hidden details.

Jill Biden wore a dress from another American designer

Markarian founder and designer Alexander O'Neill told Insider that she hopes the first lady will continue to represent up-and-coming, American designers.

"I love that her focus has been on emerging designers so far," O'Neill said. "I think she recognizes the power and impact that her clothing choices have on emerging talent."

For the concert, Biden wore an ivory outfit from Uruguayan-American designer Gabriela Hearst.

The first lady also chose to highlight an American designer on the eve of her husband's inauguration. Biden wore a magenta dress and coat designed by Jonathan Cohen, a New York-based designer that is known for his sustainability and zero-waste design efforts.

Biden's ivory dress and coat featured hand-embroidered flowers for every US state and territory

Hearst shared on Instagram that each flower took between two to four hours to embroider.

"The message of Unity is the main inspiration for the creation of the Ensemble," Heart wrote. "Unity makes strength and it is needed for the road ahead. The blooming symbol to represent this message are the federal flowers from every state and territory of the United States of America."

Delaware's flower was placed close to Biden's heart

In the same Instagram post, the designer shared that the Delaware flower was embroidered at the heart level of the first lady, and then the rest of the flowers branched out from that point.

Delaware is an important place for the first lady, as it's her home state. She also got her bachelor's degree and her doctorate from the University of Delaware and was a teacher at the Delaware Technical & Community College from 1993 to 2008.

The coat had a hidden quote hand-embroidered on the lining

Hearst revealed on Instagram that a quote by Benjamin Franklin was stitched into the coat to represent Biden's role as an educator.

"Tell me and I forget. Teach me and I remember. Involve me and I learn," the quote reads.

Biden's entire outfit was made in NYC from sustainably-sourced materials

Part of Hearst's mission with her namesake label is to create clothes as sustainably as possible. She uses wool from her family's sheep farm in Uruguay, according to her website, and Biden's look was made with fabrics the brand already had.

The designer and Biden actually have a long history together. The first lady wore a silk, fringe-trimmed green dress from the designer to a presidential debate in September, and Hearst even designed a T-shirt for the Biden campaign.

The first lady paired her outfit with a corsage, and people think it was a gift from her husband

As Insider's Samantha Grindell reported, Jill Biden was wearing a white corsage on her right wrist that coordinated with her outfit. Many fans think President Joe Biden gifted her the corsage ahead of the Inauguration Concert.

Jill Biden is not the first, first lady to wear a corsage during an inauguration celebration, though. Mamie Eisenhower and Betty Ford both wore the floral accessory during their husbands' swearing-in festivities, according to Vogue.
