I ride in cycling gear. I value the comfort and durability of the cycling clothes (plus not having my office clothes all sweaty and stinky) more than I do the convenience of showing up to work already dressed and ready work. Plus, when it's 95 degrees with 85% humidity in July, riding in office clothes is NOT a pleasant experience. On top of all that, since I am a year-round commuter, I need clothes that will meet my needs in any weather conditions, and my office clothes certainly can't do that.
