Anyone can wear a cross necklace if they wish to. While it is often thought of as a religious symbol, it has gained popularity in modern society purely for its simplistic design and potential personal meaning to the wearer.
You are able to wear cross necklaces anywhere that jewellery is permitted, regardless of your religion or gender.
If you're wondering "Can you wear a cross necklace to work"? The simple answer is, yes, you can. In fact, if worn for religious purposes, you are not allowed to be asked to remove your cross pendant due to discrimination laws.
The only exception to this is if you work in a job where necklaces cannot be worn for health and safety purposes. Workplaces like these often only permit a single, plain wedding band as jewellery with no exceptions.
