I opened the bottom and here is the draping, I was impressed how the shoulder parts act when the shopping bag has a doubled layer on the handle. It creates a shape that extends to the surface and twists into the shoulder.
For fitting, I put two darts in the front.

Putting equins
I use spare fabric from the last shirting project to make this pocket in the front.
I use two yards plain cotton to make the dress.
For the bottom I put elastic bands to gather the fabric vertically, and attach the bottom hem up.
