Prefer to wear a suit instead of a tuxedo? What's the difference anyway? A tuxedo will usually have satin fabric on the lapels of the jacket and a satin accent on the leg of the trousers. A formal suit will not have the satin accents. Either option can be worn to weddings, proms or special events. Don't forget to accessorize your suit with a dress shirt and a bow tie or necktie.
