There's also the issue of weather. Many of us live in places where it rains, heavily and frequently. Or it's extremely hot and humid and the result of walking is that you arrive at your destination soaked in sweat.
I love to get out and walk in my neighborhood whenever possible, but walking even half a mile in the summer heat in Atlanta in work appropriate clothing is going to wreck your appearance.
I used to live in the south (New Orleans) and their idea of work appropriate clothing is absurd for the weather. Long sleeves, ties, etc. Worst part is that no one wants to wear them, so they buy the cheapest, sloppiest looking version of them, which is worse than just letting people dress casually.
