The inaugural hat was like nothing so much as the broad-brimmed white hat Mrs. Trump wore during a state visit by French President Emmanuel Macron and his wife in 2018, which likewise made waves and which she auctioned off in 2022 as an “iconic broad-brimmed one-of-a-kind hat.” Her reference was herself.

Sports radio legend Mike Francesa reacted to first lady Melania Trump's outfit on Inauguration Day, saying he loved her style but was no fan of that hat.

How viral was the hat? Global searches about what first lady Melania Trump had on her head were briefly higher than for President Donald Trump’s speech.

Eric Javits, the designer behind the viral hat worn by Melania Trump at the inauguration, told "CBS Mornings" he wasn't sure if the first lady would wear it due to the venue change.
