I know the 1/2 circle cloak was common.
I know the 3/4 circle cloak existed, and is common with reenactors.

Is there any evidence of 1/4 circle cloaks?

I'm trying to recreate one of the cloaks in this image.

It way very well be a 1/2 circle cloak. I'm assuming the consensus will be that it is a 1/2 circle.
But using muslin and my Ken doll, I've been getting the most similar silhouette with a slightly offset 1/4 circle.

I'm not certain about 1/4 circle cloaks. But what everyone assumes is my square cloak is actually more of a trapezoid with a rounded bottom edge. It hangs kind of like the picture you have.

That is a half circle. The line going up and down each side of the body is the straight line cut. I have a half circle and that is exactly what it looks like when worn.
