Dr. Jill Biden, the former first lady, continued her custom of donning American designers as she picked a Ralph Lauren wrap coat for Donald Trump's inauguration

Fashion was front and center at Donald Trump’s second presidential inauguration. With high-profile figures like Melania Trump, Jill Biden and Kamala Harris in attendance, Monday’s festivities featured a slew of well-dressed women ready to make a statement.

Just ten days ago, at Jimmy Carter's state funeral at Washington National Cathedral today, all five living U.S. presidents attended: Bill Clinton, George W. Bush, Barack Obama, Donald Trump, and Joe Biden. Today, all five men were once again in the same place, as Clinton, Bush, Obama, and Biden attended Trump's inauguration.

First lady Jill Biden and President-elect Trump surprised observers in December after appearing chummy at the reopening of the Notre Dame Cathedral in Paris — and now the former first lady has revealed what the pair talked about in that viral moment.

Inauguration Day festivities brought plenty of high-profile style on everyone from incoming political figures to inauguration performers. "Good Morning America" is taking a closer look at the standout looks of the day from Ivanka Trump's sleek, deep green ensemble to Usha Vance's soft pink coat with a matching scarf.

A pastor, his eyes closed, preaches his heart out for history. A former president spots an acquaintance, then grins and winks.

My family has been subjected to unrelenting attacks and threats, motivated solely by a desire to hurt me—the worst kind of partisan politics.  Unfortunately, I have no reason to believe these attacks will end.

The inauguration is really about swearing in the next president, but first ladies throughout history have stolen the show with their inaugural gowns.

Who do you think is more disappointed to see Melania Trump as First Lady redux? Her husband’s detractors? Or Melania herself?

Ahead, we break down 21 of the best Inauguration Day looks of all time, from Lady Gaga’s subtly patriotic Schiaparelli dress to Jackie O’s Halston hat and Oleg Cassini coat.

The guest list includes some of America’s most influential tech billionaires and politicians as well as some foreign leaders and celebrities who have embraced Trump.
