It will very much depend on the weather, what you will actually wear on the slope, and on your proficiency as a boarder. A snowboarder-trouser is wider cut and more comfortably tailored than the average skiing-trousers. Both are of water-resistant material. Underneath those trousers wear a pantyhose- either of wool or - in very cold weather, a knee-length panty of angora-wool over a thin pair of nylon panty-hose. Wear thick woolen socks and the boarder-boots.
Very important are the special snowboarding-gloves. They may be leather, but other material will do as well. Make sure they have a rubber-rough-lining on the palms, you will use your palms to stop your falls. So- even if you use normal skiing-gloves, they will not last a day of snowboarding if you are a beginner! Your snowboarding anorak is extra-long + has an inside fastening to go tightly around your bottom - so snow will not get inside when you fall. Underneth this anorak, wear any comfi flannel-shirt. Now, you still need a hat- again- if a beginner, get one that fastens under your chin - or you'll keep searching your hat in the snow at all times when it goes flying as you fall!
