Well, the skirt section is a pattern I made myself. It's made of seven panels, sewn together for the black underskirt and left separate in the silver. The panels aren't all the same, I tried to angle them so that it would stick out more in front like a Dalek does, but that ended up only working if I hold perfectly still. It will probably work better for you! The bodice of the dress is from McCall's 5806.
