French cuffs are hott like toast in the Tropic of Cancer. Wear them, dude. Skip it if you're under 5'8" -- it'll break up your body line more than you can afford; if you're short, you want your arms to look as long as possible. But otherwise, yeah.
You of all people should know, though, that they were developed by Napolean (or one of his cohorts?) so that his military men could wipe their runny noses in them and not have to bother with a handkerchief But I don't think many men do this anymore.
