An odd question on yahoo answers. Still, I got the best answer! =)
Its not a very common item you can find in a mall. But you can have one customized by a designer or fashion house that specializes in bridal wear and gowns. I remember a cousin of mine had a parasol made of lace and a veil made for a stage play along with a black hat with a veil-like fringe for a funeral scene.
Provide a sketch or photo of the item so they can create the effect you want.
