I ride in full on cycling gear to work then take a shower and get into my work clothes (jeans, polo shirt, sneakers) once I get there. I take a full set of clean clothes including socks and underwear in advance to the office but once my Dynapack DX gets here I'll just take it with me the day of riding. I'm lucky that we have a shower, I have my own locker and office as well as a full fledged bike rack inside the building for bike storage. I work at a biker friendly office. My commute is 15 miles one way.
