Hi there, that’s an awesome costume! If you have a JoAnn’s near you, check out their collection of silky fabrics. This is like a faux silk fabric that’s synthetic fabric but it’s extremely light weight and I think it’ll give you that beautiful draping that’s in the shroud. If you have trouble finding it in the store, ask an employee for the location of the polyester silky fabrics in solid colors. They’re usually grouped together on their own shelf. Please post a pic when you finish your costume 🙂
