Halakhah zu Jechezkiel 23:31

And similarly, (the Sages) decreed on the crowns of grooms not to wear at all, and not dress the groom on his head with any wreath, as it says "Remove the turban and lift off the crown" (Ezekiel 23:31). And similarly it was decreed on the crown of a Bride if it is silver yet of thread is permissible. And this is specifically on a bride and groom, but other people, men and women, it was not decreed.
