Bonnet. [From Hindoo banat, woolen cloth or broadcloth] A form of head-covering worn by women out of doors. It encloses the head more or less at the sides and generally the back, and is usually trimmed with some elaborateness and tied on the head with ribbons. It differs from a hat of the ordinary form in having no brim. In Scotland the term bonnet is applied to any kind of a cap worn by men, but specifically to the closely woven and seamless Scotch caps of wool, known as glengarys, balmorals, braid bonnets and kilmarnocks. In England about the year 1480, extravagantly trimmed bonnets were worn by men as well as by women. These were usually made of cloth, sometimes richly adorned with feathers, jewelry and ornaments of gold. It was regarded as a grave breach of propriety by the law-makers of this period for a married man to indulge in these fanciful bonnets, and in consequence a law was enacted that " if any sane person, of full age, whose wife not being divorced, nor willingly absenting herself from him, doth wear any French hood or bonnet of velvet, with any habiliment, paste, or edge of gold, pearl or stone shall lose ,£10, for every three months " during which time the law was disobeyed, for the evident purpose of "protecting" the rights of unmarried men.
