The black tulle also came a couple days ago. While I wait for the black silk to arrive, I'm working backwards, so I started on the overskirt. I've started with two layers of tulle, pleated to attach to the bodice. The dress from the movie closes at the back, but I'm going to make it have a front closure to make it easier on myself - both in general fit (it's more forgiving if you change size a little) and ease of dressing. I think I'm going to add two more layers because as of now it doesn't look luxurious and pouffy enough, but yikes, tulle is a nightmare to cut properly. It has so much give. To help in cutting, I laid it out on the carpet and stuck pins into the edges, down into the carpet. It helped make the fabric more stable and less slithery. After pleating, I sewed down the pleats on the machine and zig-zag stitched the edge to keep it more orderly.
