An Australian fashion firm has developed a motif for singles to attract an eligible partner.

Perth-based SHI Symbol International said the symbol, which has been developed for jewellery and T-shirts, is for the singles of the world interested in meeting others.

The company said the symbol is designed to say the wearer is single and not emotionally or physically involved, happy and ready to meet like-minded people, and interested in "at least saying hello".

The SHI Symbol is based on linking the male Mars and female Venus gender symbols.

Symbol International said it has received an excellent response from Perth singles since releasing the concept, and that visitors from UK, US and Scotland were now wearing them back at home.
