Plain capes are just straight pieces of fabric without any tailored fitting or decorations.
Even when sewing a cape dress with a plain cape, there are still many ways to style the cape.
The different style options are described on the page about cape dresses.
This gallery shows a collection of plain capes with different styles, like loose fitting, wide or narrow, straight or rectangular.
The same dress is shown with differently styled capes for easy comparison.
