If you have to go black tie, don't rent. You're out of high school right? Time to get a tux. You want something that'll fit right and can get tailored over the years as your body changes. Make it black, and you can't go wrong with peak lapels. The difference between a proper tuxedo and a black suit? Satin details like the tuxedo stripe on the pants and on the lapels. Shawl collar tuxes have made a comeback with rappers and celebrities, but when it comes to things like this that probably won't get a lot of wear, timeless trumps trendy.
