Then I found a fun shop on Etsy called Beadmask and saw the Raven Queen Jewelled Leather Mask.Incredible piece isn't it? I would love to wear a black tulle gown and be the Raven Queen for halloween! Here are a few of the gowns I think would love to wear; a little more glamourous than my first costume idea...
