I finally got the pattern for this dress finished and uploaded.
I usually wear a size 6-8 in dresses, or medium in most clothes.
This is a pretty roomy dress, contained by a belt, so it would probably work if you were a size larger.
To change it to be larger or smaller, I would just shave some off/add some to the fold line, adjusting the neckline to be the same.

2 1/2 yards fabric (should not be stiff fabric, flowy would be best)
If you are unsure how to understitch, here is a great tutorial.
