Oddiyanam
The South Indian waist belt, rigid and heavily worked, worn over a saree at the hips.
An oddiyanam is built in linked panels so it flexes around the body while staying structurally stiff.
It is among the heaviest pieces in a South Indian bridal set, frequently in temple style with a central Lakshmi panel.
Vaddanam is the Telugu name for the same ornament.
When you are buying
Weight and waist size both matter, and neither is adjustable by much. This is the piece most often rented rather than bought outright.
