There ARE none for the boots and the back of the outift beyond what I got doing a pause-screenshot-go-pause-screenshot-go of her 3 second scene in the trailer. The back of the corset is really the only thing I didn't have at least sketchy reference for.
Thank you so much for your reply. I was doing the exact same thing with the trailer and the back of the corset is really hard to see, sucks big time. You did an amazing job with the outfit though especially with only having a few reference images.
I took MANY photos of the process of making this. The cosplayer is going to put it all together in a "How to" blog post soon. If you want to catch that, go like my page on FB and/or hers. The links are in the description of the above photo.
