How would you feel about drafting the pattern yourself ? The artwork is fairly realistic in that there are seams where they need to be seams - that will be functional and work well. Even the sleeves are rendered fairly realistically and would probably just need some kind of fashion tape or glue to stay up if they proved difficult.
If you're not sure about making it yourself, you could look for a fitted pattern with princess seams and go from there.
