Sewing pattern which I used for making this dress in the picture.
Sizes 36-42
This dress is made from two parts: 
Tulle skirt
Bodysuit
The dress is made from two parts that the sewing and fitting would be easier. A bodysuit makes the dress more fitted and comfortable. It's easier to move it stays in place while wearing. it won't go up while dancing or moving.
It is very important to choose the correct material for the bodysuit. Use only stretchy lycra fabric. 
For the bodysuit, I used 4 ways stretchy lycra fabrics - baby blue color.
I cover this fabric with  white flower lace. 
For the straps, I use silk fabric.
For the skirt, I used soft tulle. I sew the underskirt from non-see-through soft chiffon.
