I made this necklace to be worn with shirts like the “T-Shirt style”. It fits nicely to the size of this kind of shirts. The crescent moon and star is an internationally-recognized symbol of the faith of Islam. The symbol is featured on the flags of several Muslim countries, and is even part of the official emblem for the International Federation of Red Cross and Red Crescent Societies. I made another one that fits nicely to shirts of the “Loose Button Down type”
