I normally transform from professional to man of leisure whilst driving home from work.

Wearing my choice of clothing vs. a restictive dress code is the universal signal of freedom. I will literally change out of a suit and tie and into shorts and flip-flops while driving my car home. I've had people meet me at work, then follow me to a 2nd location, and look at me in wild amazement as I step out of my car dressed like it's Spring Break. It's a gift.
