I commute all year round and I decided to try switching from wearing full-on waterproof clothes to the quickest drying things I could find.
So far, very pleased with my Giordana Body Clone jacket (

I bought some Teva churn shoes, which are not particularly warm, but great for three seasons in that they also dry very quickly. I still wear overshoes over them on the wetter days though. I've been through a few different makes of overshoes - The Pro ones I had were good waterproof and very warm, but the thicker neoprene was less flexible, which meant they seemed to get tatty quite quickly (still lasted me a couple of years) The Primal Crankenstein ones look excellent, but were terrible, with the inflexible hard rubber bottoms making them very hard to take on and off and the seams leaking from the very first ride. At the moment I have some Giordana ones (these I think:

In terms of gloves, apart from in winter I tend to wear thinner ones again, excepting they won't keep my hands dry in prolonged rain, but that they'll always be dry in time for the next journey.
I hope some of that is of use!
