White Shirt

A crisp white shirt can go with anything from a regular suit to a formal tuxedo. You don't have to cop one of those tuxedo shirts with the weird frills on the chest, just opt for a spread collar and a substantial cotton fabric. This shirt from Ovadia & Sons features mother-of-pearl buttons and more formal barrel cuffs, but it can be easily dressed up and down.
