Many online instantly took note that the former president’s black bomber jacket, which some social media users have already begun referring to as the “O-bomber,” has the number “44” stitched on its sleeve in white lettering. The number is a reference Obama’s standing as the nation’s 44th president.

The look has since garnered much applause from many online who were asking for website addresses to purchase the “merch.”
