This is a very attractive stitch. According to Barbara Walker, this stitch was used in a vest (undershirt) for King Charles I, which he wore on the day of his execution.

You can see a photo of the vest (bloodstained) at the at getty images. It is worked in very fine silk. Imagine that amount of work for something worn for a decapitation, yikes!
