If its with friends or people you want too look good around wear some kinda thick leggings with loose cute jeans over it. Whatever shirt, either a cute jacket or coat something not too heavy or bulky. For shoes you could wear some fuzzy boots like uggs or whatever matches the outfit, thick socks that wont make your feet be crammed into the shoes cuz that actually makes your feet colder (weird but true). If its with people that you don't really care if you're cute or not then some sweatpants, boots, thick socks, warm coat. Hope this helped
Fire proof and washable clothes. You will end up smelling of smoke and ashes and will want it out. QUICK. (I should know, I've been to one! :/). If its with some one you want to think that your cute, thick leggings, colorful sweat pants, or nice jeens. A cute sweat shirt, long sleeves top, or a nice t shirt w/ a cute jacket or a thicker t shirt and a light jacket. Dress warm and have a nice time! :D These will also work if you are with people you don't care about. Nice boots or sneakers can work for shoes.
