I'm on the opposite side. I never cycle in work clothes. My cubicle drawers are full of my work clothes :-) that I refresh either by carrying replacement in my handlebar bag or on a mass scale once every few weeks whenever I go by in a car.

I wake up, don't shower, get into my biking clothes and bike to work. It used to be 14 miles one way. Now it is 20 miles one way.

Get to work, take a duffel bag with my work clothes, shoes, shower kit and a towel and go take a shower. I dress in clean work clothes and feel great.
