Okay, now I get it. I had to download the document and zoom in to see the hat worn by the student on the right:
It's not really the same kind of hat as a poofy beret. It has a chinstrap and a second layer around the edge that flattens the outside the perimeter (it might be metal, but I'm not sure, there are some crowns that are designed like this, metal on the edge and a pushed-down fabric in the middle, crowns from Graz are sometimes designed like this, but without a chin strap). A beret poofs out on the sides and never has a chin strap (it's not really called a beret if it has a chinstrap).
Hmm, I'm still trying to figure out this headgear. It almost looks like a prince's crown worn over a night-cap.
I suspect it's a chinstrap crown on the boy's head. Here is a fancier one from Germany with a flat top and a chin strap:
