If i can add my prutah to this discussion…
Monday was originally a homage to the moon, the sun for sunday. Today, nobody gives a garden of fig trees, it’s just a day name for everyone. Can that be applied to today’s hat style?
Moreover, the streimels that are worn come from eastern europe and lots of cossacks, polish and russian commoners and others wore thosr furry hats.
I don’t believe the origin has meaning. The intent of the yid wearing is their own.
