Michelle Obama Wows in Pant Suit by Black Designer at Joe Biden's Inauguration

Joe Biden was sworn in as the 46th president of the United States and Kamala Harris was sworn in as the first Black, first Asian-American, and first woman to take the oath of vice president. And Michelle Obama came impeccably dressed for the momentous occasion.

The former first lady arrived at the Biden-Harris inauguration looking like an actual superhero in a plum coat and matching pant suit. Obama's was one of many monochromatic looks in the fashionable crowd.

Obama's look was designed by Sergio Hudson, a Black designer from South Carolina. ET has learned that Hudson also dressed Vice President Harris for an event later in the day.

Obama accessorized her outfit with a black face mask and black leather gloves. Many social media admirers commented on the former FLOTUS' luscious curls, unaffected by the winter weather.

As Obama's stylist Meredith Koop later explained on Instagram, a lot went into crafting her look for the big day.

"Now, let’s break this down. This is not a jumpsuit. It is gorgeous separates from the exceptional @sergiohudson," she wrote. "I’ve worked with hundreds of designers on custom looks both in the US and internationally, and I can say confidently that Sergio is in the top in his designs, construction and understanding of how to dress the curves of a woman’s body. This was my 3rd look with him and he absolutely blim blam killed it. I pulled references from his collections to start. With him, I don’t have to explain too much. He gets it. All of the sketches he sent were gorgeous and it was hard to choose."

Koop revealed that she knew Obama would be wearing "practical, beautiful pants" for the event. While some assumed the color of Obama's ensemble was a symbol of bipartisanship, Koop said it "wasn't the intention."

"I had gloves and shoes along with a mask dyed to match, but I decided last minute to do @christyrilling black silk textured mask and @stuartweitzman black suede boots with a block heel. It felt modern and more how women tend to dress," she added.

We can expect more fabulous looks from Dr. Jill Biden, Kamala Harris, Lady Gaga and others, as well as moments from the historic inauguration and succeeding events. And later, a television special Celebrating America, hosted by Tom Hanks, will feature performances by John Legend, Tim McGraw, Justin Timberlake, Demi Lovato, Jon Bon Jovi and more.
