A tuxedo jacket features a peaked or shawl lapel faced with silk (or a silk substitute), whereas most business suit jackets use notch lapels faced with the same fabric as the body of the jacket. The tuxedo's trousers have a silk stripe running down the outer seam of each leg, again contrasting with the trouser fabric itself.
