...and yours emanates the stench of fogeyist anachronism. The trousers of a formal suit may be plain bottom (like all of them, a breakable rule), but since when is a RLBL suit formal?
Here are the facts: today, either are "acceptable", whatever that means. Cuffs (1.5"-2.0", depending on your height) help trousers drape better due to the added weight at the bottom. But they also make your legs look shorter. Decide which matters more to you.
