This was a fun costume to make and not too difficult either. Certainly worth the effort considering how excited people were when they saw it.
Step 1: Creating the torso
The ball is for a Kirby costume we made at the same time.
In front you can see the torso we made. I used a fedex box and solo cup for the neck then paper mached it together along with a couple of shoulder bumps. These are important for holding the dress on.
