I sweat way too much to wear my work cloths during my commute, especially during summer months. Most days I leave the house in MTB shorts and a short sleeve t-shirt, sometimes with a Pearl Izumi vest. I'd rather be a little cold to keep the sweat down. I also ride on an old brown leather saddle, which would leave a mark on my khakis/pants. I don't have an aversion to lycra, but save the full road kit for longer non-commute rides.
