An anklet, ankle chain, or ankle bracelet is an ornament worn around the ankle. Barefoot anklets and toe rings historically have been worn for centuries by girls and women in Egypt and Arab world especially in Bedouin and countryside and married women in India, though in the United States both casual and more formal anklets became fashionable in the late twentieth century.
While in western popular culture both younger men and women may wear casual leather anklets, they are popular among barefoot women. Formal anklets (silver, gold, beads) are common women's fashion jewelry. Anklets are an important jewellery in Indian marriages worn along with saris.
Left or right?
In India, anklets are worn on both ankles. However, outside India most anklets seem to be worn on the right ankle. Perhaps this is due to more people being right-handed. Although in eastern cultures, anklets are worn on both ankles. Worn on the right ankle it may indicate a "hotwife" or cuckold's wife, though this is not universal by any means. But a woman at work told us she only wears it on the right due to obvious reasons - but we must be stupid because we obviously couldnt figure it out.
