A typical outfit for a day in the snow...?

You will need warm boots that are waterproof at least on the lower part of the uppers or at the very least something like a big pair of wellies with warm wool sox in them, maybe two pairs at once. A set of poly prope longjohns that fit under your jeans would be cheapest, maybe one bottoms and two shirts if you will wear them all day every day. A lot depends on what activities you plan to do. Some sort of snow pants or snow mobile suit if you plan to toboggan, snow shoe, x-country ski or the like. A good pair of mittens made for snow sports and a hat with ear flaps or ear muffs or you could put a hoodie under your jacket. Check out the resale stores you may find some real bargains as folks often get new stuff for Christmas and put the old stuff in Goodwill to get it out of the closets. If you will be winter camping then that is a whole nother list and too long to go into. Ask your friend who invited you if they have any loaner stuff you could use. Our house always has a few extra sets of mittens and hats for friends who want to go out and play in the snow. Have fun.
