Traditional Black Tie Attire consists of a black tuxedo jacket, white dress shirt, either a cummerbund or a vest, a black bowtie, and polished black shoes. Most tuxedo jackets these days are single breasted. The lapel you choose is a personal preference. Most popular tux jackets are the notch lapel, but peak or shawl lapels are also common choices. As far as the dress shirt is concerned, the biggest difference lies in collar style as well as a pleated or non-pleated front. Of course you can always spice up your look by adding a few accessories like a white pocket square and a set of classy cufflinks.
