Both suits and tuxedos are considered formalwear, but tuxedos are largely considered the more formal of the two. Many people actually wear suits on a regular basis for work, whereas tuxedos tend to be worn for evening events as well as black-tie formal occasions. Many men will wear a tuxedo only a few times, but a suit can be worn for a meeting, a date, or simply worn to work on a regular basis during any time of day.  Suits can be paired with any number of different dress shirts as well as a slightly more casual show such an an oxford, whereas tuxedos are traditionally paired with a white shirt and black patent shoes. Traditionally speaking, the main visual difference between a suit and a tuxedo is the addition of satin details in a tuxedo. Tuxedos tend to have satin facing on the lapels, satin buttons, as well as a satin stripe down the side of the pant leg. A suit will have jacket, lapel, and pants all made of the same fabric. In a suit, the buttons will either be made of the same fabric as the jacket or often they will have plastic buttons. Ladies can rock both, suit rentals and tuxedos, they look great.
