When you're commuting short distances, it's more practical to dress for where you're going, not for the ride.
Advantages to cycling gear are comfort, visibility and safety. Wear whatever feels best to you, that's what I do. If you're just riding around town, you can wear most anything. On longer rides, the advantages of the shoes, shorts and jersey become more important. You can walk around town in a business suit, but you wouldn't go hiking in it.
