Commuting Distance?

[RoadRaven]

For those of you who ride longer distances, what do you prefer to wear? Do you get all decked out in jersey, fancy shorts, clipless shoes, etc? Or do you just go T-shirt and shorts? Or even wear work clothes?

I always wear bike shorts and jersey... as my distance is over 20kms each way and I commute on my race bike there is no way "normal" shorts would be comfortable for sitting.

I leave work clothes at work, as well as towels, shampoo, soap and deodourant.
