I wear my dress clothes except I keep the collared shirt in my bag. My ride to work shirt is a white t-shirt I've wet before I leave. Go into a rest room and change when I get there. 3 minutes. It's been 103+ degrees here in KY and no problem. When my commute was longer, I'd put some wintergreen alcohol in my bag and rub down with that. Part of my advocacy effort is to make commuting look fun and easy to people who might be on the fence. There seems to be a preconception that you need all kinds of specialized equipment or routine. Keeping stuff simple and inexpensive is a good way to do that, in my opinion.
