They don't play in trousers anymore, so appearances don't really matter as much as in the 19th century.
They don't towel off because of perspiration most of the time. They towel off because it's become a force of habit, a compulsion. Most players towel off between every point, including aces. It's a subconscious way of resetting themselves for the next point. Players do other things as well: Roddick tugs on his shirt, Sharapova pushes back her hair on both sides, and Nadal...does what he does.
