I was not referring to any kind of fashion. I wanted to wear the mezuzah necklace (not the doorstep mezuzah) for protection and good luck. Can u suggest me something else if this is not possible? I wanted wear something that will have the blessings and protection of Elohim against evil.

Shalom, Thanks for getting back to us. I understand that you want to wear something for a blessing and protection from G-d against evil. In Judaism we do not have such a concept. We believe that protection comes from G-d when a person keeps His laws, and acts in a correct way. The more a person perfects themselves, becoming what we call a “Tzadik” – a righteous person – the more divine protection they warrant. I hope this is of some help to you, Blessings.
