ghumghata | घूँघट

The end of a sari or cloth used to cover the head and upper part of the face out of respect for elders or others deserving respect. Covering the head with a ghumghata was done by all chaste women in ancient Indian culture.

Traditionally, in India women also cover their face when they are feeling shy.
