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
Here are patterns for the leotard and underskirt. 
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 doesn't go up while dancing or moving.
In this PDF pattern, You will find a Bodysuit and long skirt.
You will also need to measure and cut bottom rufle part Yourself. I didn't add the ruffle detail for the tulle part of the skirt because it is just a really big rectangle detail.
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 - nude color.
I cover this fabric with see-through stretchy white flower lace. Then I added more decorative thicker lace on the chest and back.  
For the skirt, I used soft tulle. I sew the underskirt from non-see-through soft chiffon.
The Pattern is in PDF format.
