One viral moment has popped up during Donald Trump’s second inauguration. Melania Trump drew rave responses for her headwear, a stylish cap with a large brim, at the event, which is ongoing at the United States Capitol rotunda in Washington,

American designer Adam Lippes designed Melania Trump's ensemble, which consisted of a navy silk wool coat, a navy silk wool pencil skirt and an ivory silk crepe blouse.

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.

He explained that after the show, he would ask the audience who wore the hat better, "me, Melania or the Hamburglar." Fallon wasn't the only one — social media had already exploded with references to the hat worn by the popular McDonald's character.
