A men’s suit and a tuxedo are usually designed differently and worn in different settings. A tuxedo tends to be a pretty standardised style of suit that’s worn at formal evening events with a black tie dress code. They tend to be black and feature satin or grosgrain lapels and are worn with accessories like a cummerbund, bow tie and dress shoes. Regular suits tend to have more variation when it comes to cut, colour, fabric and style, and you can wear them to work, weddings and events.
