We spend hours on our hair every week so it's only natural that we don't want to come down with a serious case of hat hair every time we walk out the door. Our alternative: a hot pair of furry earmuffs!     Marni understood our plight for fashionable, warm and hair-friendly headgear this fall and topped off models' heads with luxurious fur earmuffs.     Topshop's fur earmuffs are just as cute as Marni's and for all you PETA members, they're totally faux (and a steal at only $24!).
