What is the ruling on a man tying his short hair with women's iron clips? What is the evidence that wearing bracelets and necklaces is specific to women, given the widespread wearing of trousers by women? And does wearing necklaces and bracelets affect the validity of fasting?

It is not permissible to tie hair using the usual and well-known methods for women, due to the forbidden imitation involved. It is not permissible for a man to wear bracelets and necklaces, as this constitutes imitation of women. Therefore, imitating women by wearing their specific attire, such as bracelets and anklets, is forbidden, unlike a ring. The evidence for these items being specific to women is custom and common practice. As for trousers, both men and women have types that are specific to them.
