I do know the shoes should match the belt because my father told me so. He also told me there is one tuxedo color, and that is black. When I went to my high school prom in 1979 many wore white, powder blue, and even yellow tuxes. Two buddies of mine and I were the only 3 in black and dad said "You, Jed, and Glenn will be the only ones able to look at prom pictures in 10 years and not be embarrassed as hell" One of my friends wore a white tux with top hat and tails and dad told him "I had no idea the circus was in town"
