I'm too cheap to buy cycling specific clothes. I usually just order some decent duofold from whomever has it on sale cheapest. I have some medium weight short sleeve wicking matl. t-shirts that I bought on sale from a local sporting good store, and will put one of those over a lighter weight long-sleeved t-shirt if it's a little chilly. Maybe a windbreaker if it's really chilly (I have one that stuff into it's own pocket). Looks very "Freddish", but feels very comfortable!
