Create drapes surrounding this shape using pen tool. We used two colors - orange and grey - you can use different colours to suit your project or work.





Similar to the step above but creating the bottom slope for balance. Also overlaying with multi-level drapes as well.





Select orange shape layer at the right. Double click the layer to open layer style window. Apply layer style with the settings shown.






Similarly apply gradient overlay on the rest of the orange and grey layers. Play around with their gradient angles according to the shape of drapes.
