Just be sure whatever you go with you can layer on/off easily. Depending on the length of your ride, time of day, wind direction etc etc you'll need to be able to vent or even remove layers or close up or put layers back on. My commute this AM at 31 I wore an REI MTS LS base layer, a LS jersey on top and my IllumiNITE cycling jacket. Bottoms were fleece-lined leg warmers, shorts and tights, feet-heavy socks and toe covers, hands Canari heavyweight riding gloves. I had a fleece headband on my head. My ride is 6 miles all downhill going to work and I was still a tad chilly went I got here. Going home is all uphill so a couple of those layers will get packed. Last year when I first started commuting in the winter, I bought 2 LS jerseys on sale, a jacket and some long underwear and made it all winter with that. When it got really cold I just wore the long underwear, both jerseys and the jacket. Leg warmers, shorts and wind/rain pants on the bottom. I added tights on the Really cold days. (I was much poorer last year and made do with what I could). Hope that helps.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
