A tuxedo is traditionally more formal than a suit, often featuring satin detailing on the lapels, buttons, and side stripes of the pants. Tuxedos are typically worn with a formal dress shirt, bow tie, and sometimes a cummerbund or vest, making them a popular choice for black-tie weddings. Suits, while still elegant, have a more understated look without the satin accents and are often paired with a standard necktie. For wedding parties seeking a timeless, classic appearance, tuxedos offer an elevated level of sophistication.
