The term 'MAN's formal wear' is often associated with the 6-letter word 'tuxedo'. A tuxedo is a type of formal evening wear, typically worn to a formal event such as a wedding or a black-tie dinner. It is usually made of black or midnight blue fabric and is characterized by its satin lapels and buttons. The tuxedo is traditionally paired with a white dress shirt, a bow tie, and a cummerbund or waistcoat.
