When it's really cold (30s or less) I wear and underarmour base layer then a long sleeve golf shirt. Over that I wear my Footjoy merino wool performance seweater. I have a lined pullover I wear over that. I wear ski socks and a ski base layer over heavy corduroy pants. Also a wool ski cap and a fleece ski "gator" for my neck. Keeps me warm into the 30s.
