A belly chain is a type of body jewelry worn around the waist. Some belly chains attach to a navel piercing; these are also called "pierced belly chains". Wearer can adjust them across the waist by putting the fastening device at one end of the chain through one of those circles, as per her waist length.
Belly chains are quite popular amongst ladies who like to wear small shirts with low waist pants. It?s like a chain that is worn round the belly. It comes either with attached belly button or without it. Heroines doing item numbers in movies are seen wearing lustrous and shining chains. The nice thing about these chains is that they don?t need any piercing. And they look good with short skirts or low waist pants. You must have seen artists wear these chains during stage performances. The trend has yet started from there.
