What is the ruling on men wearing bracelets, earrings, and necklaces in countries where their men are accustomed to wearing them?

It is forbidden for a man to imitate women, or to imitate disbelievers and transgressors. This includes clothing. If men in a certain country are accustomed to wearing bracelets, rings, and earrings, which the Sharia has specified for women to wear, then it is not permissible for a man to wear them.
