The type of bike is a really big factor. Upright bikes, like English 3 speeds or modern European commuter bikes are designed to be ridden in normal clothing. Most bikes sold in this country (road, mountain, or hybrid) are not. Upright riding position, wide leather saddle, and a chainguard/chaincase make a huge difference. My answer is yes, you can do it, and with the proper equipment it can be the easiest. fastest, and most convenient way to commute in congested areas with little or no parking. If you want sporty, I think an e-bike might be good.
