The Hottest Item at Obama’s Library Opening? A Tan Suit.

A star-studded crowd featuring (nearly) all living presidents gathered Thursday at the new Barack Obama library towering over Chicago’s South Side to celebrate the 44th president’s legacy.

Oh, and his fashion choice on a single day more than a decade ago.

Ronald Reagan proclaimed: “Tear down this wall.” George W. Bush grinned in front of a “Mission Accomplished” banner. And Obama once wore a tan suit.

It’s ancient political history now, but 12 years ago Obama bounded into the White House briefing room for a press conference about ISIS in Syria. The national security news was overshadowed by the president’s outfit.

For a younger generation that grew up after President Donald Trump took office, a tan suit might not even register as a blip on TikTok.

But at the time, Fox News talked about it for days. Twitter (as it was known back then) erupted. And some of Obama’s colleagues in Washington denounced it.

Then-Rep. Peter King (R-NY) went as far as to call the fashion faux pas “unpresidential.” “The Audacity of Taupe,” some proclaimed it. “Yes we tan,” others joked.

On Thursday, a who’s who of A-list entertainers and political insiders attempted to resurrect the tan suit from the annals of forgotten history and reclaim it as a symbol of presidential competence — if this is still what qualified as scandal, imagine what the world would look like now.

“How y’all like my tan suit?” the Obama Foundation’s board chair, Martin Nesbitt, beamed as he took the stage to address the crowd suited up in his own tan shade.

“It was inspired by a very good friend of mine who made tan suits famous,” Nesbitt said. “And I don’t know about the rest of you all, but I thought he looked pretty good wearing his. So I decided to wear one myself.”

“You look good,” Obama said later, pointing out Nesbitt’s ensemble. “That is sharp.”

“Well, they say imitation is the sincerest form of flattery,” Nesbitt clapped back.

In the audience were several celebrities who donned similar outfits: comedian Stephen Colbert, Rep. Bill Foster (D-Illinois), NBA legend Isiah Thomas, legendary television host David Letterman and even a few local politicians, including Illinois state Rep. La Shawn K. Ford.

While some of former first lady Michelle Obama’s iconic outfits are on display in the new presidential center, Obama’s tan suit doesn’t make an appearance.

“The reason we don’t have the tan suit is President Obama gave it away when he was cleaning out his closet,” former White House adviser Valerie Jarrett told NPR this week.

NPR host Tamara Keith responded: “That means there may be a tall, skinny guy somewhere out there with an infamous tan suit in his closet who doesn’t even realize it.”
