Wear them outside as fingerless mitts, of course, but you can also wear them inside, as a great fashion piece. I see them with all kinds of sweaters and long sleeve tanks for the winter. You will definitely enjoy the extra warmth but your hands will be free to type or text. These arm cuffs/warmers are made from upcycled wool in a warm open plaid (winter white and grey) which has been felted and the buttons are vintage. I love their warm, Victorian look.
