Your bike should be an upright one with fenders and a chainguard. Most commonly available bikes in the US (road, mountain, or hybrid) do not provide any clothing protection and may require a riding posture that is not compatible with normal clothing.

This is exactly what i do. Works for me! I ride everyday, no car. Sometimes on super hot days i ride in a tshirt and change into a (rolled) button shirt when i get to work.
