How is the Jewish round hat firmly worn on the head?

Jews dress casually and neatly, don't like to wear ties, and like to wear cool sandals in autumn and winter. The way they wear small round hats, to be precise, should be called tops, because it is too small and light, slightly larger than a fist, lightly buckled on the top of the head, and pinned to the top of the head with a clip for women's hair. Bald people have to transfer the edges of some hair.
