I recently purchased the updated Digi-El base and one of her clothing assets. I'll provide what I have here, as well as include a list of some remaining assets that I've found on booth but don't have yet. If anyone has assets for Digi-El that haven't been found in this thread yet or additional compatible assets they'd like to add to the "Looking For" list, let me know and I'll try to keep this post updated.
