Chlamys - correct shape

[Archidamos]

Good evening. I am asking for help. Do you have patterns (sketches) showing chlamys? I know it is made of a rectangle. However, in written sources, there is information that the lower side was rounded. The front corner of the coat was rounded as well.

It consisted of a rectangular piece of fabric (most often wool) with a rounded bottom side, fastened with a brooch or a clasp (brooch) on the right shoulder or at the front, under the neck (less often at the back), and covering the left arm. The front upper corner of the robe was deliberately rounded to obtain the spiraling line of its edge, which is the only known example of the cutting of Greek garments.

I have lots of depictions of paintings on ceramics and sculptures. However, I don't want to make any mistake. That's why I'm looking for the correct shape drawing.
