Medieval girl vampire costume

Take a long flowing black dress and sow on a red meterial as the bottom part of a apron. Velvet is the best material.
As vampires are pale use pale make up or face paint. For the great effect not only use plastic glow in the dark teeth use fake blood,face paint or make up. Wear black shoes. Use black material for a cape (or a cape you can buy) with a turned up collor. Use a ripped balck vei8l for the full on effect. :)
