I was thinking I should get myself one of these. 

At least my ears would be warm. Potential muggers might mistake me for a man and not attack. You know, there are merits to being a bearded lady.
Anyway, the bearded balaclava is available from Scandinavian Grace - available in different beard lengths and colours (bespoke beard balaclavas - BINGO!).
Oh - and if you do have facial hair - DO NOT SHAVE! DO NOT WAX! Bleaching is best, baby.
