i tend to go in my birth-day suit most the time...
but in all seriousness, 2 pair of boxers, full set of thermal underwear(pants and shirt) 2 pair of pants, 2 t-shirts, one long sleeve shirt, 3 pair of socks ( 1ankle, 2 crew), maybe some warm, puffy socks, combat boots, light hoodie, denim vest, wool p-coat or if you can get a trench coat, get one, you can make it into a p-coat with some safety pins, and its like a sleeping bag that you can walk in, i love trench coats with a passion, greatest thing ever. and a hat for cold weather, keep that heat in ya know?
pants covered in patches are pretty warm, then you put a pair of regular pants under those, and thermals under your regular pants, bullet proof. then a thermal shirt, t-shirt, hoodie, denim vest, and wool p-coat, i have been out when the temp is in the negative and been just fine with all that, huddled in my sleeping bag next to a fire.
good luck out there to all of you
