I read the same thing. It wasn’t in the article at the link below because I found this for the first time just now. I’d never be able to locate the original article now because I’ve read too much already.

Still from that very article:

The speculation involved here is an uninformed view.
This is a view of jersey-type material moving up and down.
That the movement takes the shape of a square cannot be considered definite evidence of "ballistic fabric" or a 'vest' underneath.
Those on this forum who sew or work with fabrics can understand this.
