Eclipse werewolf

I was thinking of being a Mistborn for Halloween, I tried searching online to buy a mist cloak but the only one I could find was $70 so I tried to find ways I could make it on my own but all the things I found were confusing to me. My friend told me to just buy a fleece cloak cut strips in it, buy some extra fleece to overlay some straps and to make the capelet. Would that work? Or would I just look dumb?
