I used Burda 9629 views A and G. This was a very quick sew, I had the bodysuit done in one evening and the tutu in the next. I used a Lycra / Polyester from Dressew and sparkle tulle from Fabricland. I used the star sparkle tulle for the contrast on the sleeves as well. I think it looks adorable!
Itsa loves it, although I would like to shorten the tutu.
I learned an important lesson while making this: Only gather one layer of tulle at a time! No matter how much of a time saver you think it'll be, gathering multiple layers of tulle at once will just be a knotty, grabby mess. A single layer will not have anything to grab onto and will gather easily.
