Layers if it's cold. Generally 2x T shirts and a long sleeved cotton shirt. Avoid long shirts that have any extra crap around the sleeves, or any fleeces that are bulky around the wrist area as they constrict the blood flow and give you cold hands.

Also try a big fleece over the top of leathers, you'll be warm as toast then as it breaks up the wind blast that will go through the leathers vents or zips or whatever.
