Not only are they sophisticated and traditional, they're practical too.
Cuffs add extra weight to the bottom allowing the pants to hang better.
Some stores discourage cuffs because it's more expensive for them to put on, but insist on cuffs. Just make sure the pants are long enough to break on the front of your shoe, and remember fabrics will shrink. Pleats have been fashionable since 1825 and are also practical. They automatically widen at the hips when you sit down giving you more room. Pleats are classic and the combination of pleats and cuffs on trousers are a great look.
