Tan suits abound at Obama’s presidential museum opening. You know the one.

Former President Barack Obama celebrated the opening of his presidential museum in Chicago on Thursday in the company of three former presidents, several celebrities and A-listers, and a handful of tan suits.

The tailored threads seem to bea winking reference to the 2014 stirObama caused when, in his second term, he donned a tan suit during a press briefing on possible US military action in Syria. The outfit choice sparked jokes online, catchy news headlines like “Yes we tan,” and criticism from Republicans, including one lawmaker who deemed the look “unpresidential.”

As Thursday’s ceremony kicked-off, Obama Foundation board chair Martin Nesbitt walked out on stage in a taupe suit, sparking a laugh from the former president who greeted Nesbitt before he spoke.

“How y’all like my tan suit?” Nesbitt asked the crowd. “It was inspired by a very good friend of mine who made tan suits famous.”

Some celebrities and politicians in attendance were also sporting variations of the signatureoutfit. Former late night hosts Stephen Colbert and David Letterman both had a similar get-up. The Chicago Sun-Times caught photos of Illinois Representative Bill Foster, Illinois State Representative La Shawn K. Ford, and NBA legend Isiah Thomas also rocking tan attire.

Thursday’s celebration was invite-only ahead of the center’s opening to the public on Friday, which is Juneteenth. Former first lady Michelle Obama sat on stage during the event with her two daughters, along with former presidents Joe Biden, George W. Bush, and Bill Clinton. Celebrity performances included Jennifer Hudson, who sang the national anthem, Christina Aguilera, Bruce Springsteen, Stevie Wonder, and more.

The tan suit has become a punchline for Democrats in the years since the so-called scandal. During a pre-taped tour of the center that aired on “Late Night with Stephen Colbert” in May, Colbert asked Obama if the tan suit, which he joked was one of the president’s “greatest blunders,” was going to be a part of the museum.

“I own that tan suit proudly, brother,” Obama quipped back. Colbert then presented the former president with a photo of him in the infamous outfit, to which Obama said, “I look great.”

“When you look back at the tan suit, what occurs to you?” Colbert asked.

“Fly,” Obama said.

The Sun-Times reported Thursday that the tan suit is not on display in the presidential center, per Obama Foundation Chief Corporate Affairs Officer Michael Strautmanis.
