Vaddanam ( Vaddanam / Kamarbandh / Tagdi / Oddiyanam / Kayiru / Vanki / Kandora / Kardhani / Sonta Patti) is a traditional waist belt worn by women in South India, particularly in the states of Andhra Pradesh and Telangana. It is also known as a waist chain or waist jewelry and is typically made of gold or silver.

The vaddanam usually consists of a thick chain that wraps around the waist and is fastened at the back with a hook or a clasp. It is often decorated with intricate designs and embellishments such as precious stones, pearls, or intricate filigree work.

In South Indian weddings, vaddanam is an essential part of the bride's jewelry and is often passed down from one generation to another as a family heirloom. It is also a popular gift item for special occasions such as birthdays, anniversaries, and festivals.

The vaddanam is not just a piece of jewelry but also has cultural and religious significance. It is believed to enhance the beauty and grace of a woman and is often associated with auspiciousness and good luck.
