Woah I'm posting this late.
This was my Halloween costume this year! I looked all over and finally found a fabric that was appropriately shiny. It is basically a draped dress with the straps giving it support.
The rivets were metal buttons that I found and spray painted a more silver color. The headband was my favorite part. I spray painted a funnel and super-glued it to a headband I already owned.
And the back:
Unfortunately I don't have a picture of the length but It ended right about knee-length.
As always comments and criticism welcome!!
