A langa voni (also called "pavadai daavani" in Tamil or "laṅga davaṇi" in Kannada) is a traditional dress worn in South India by girls between puberty and marriage.
The modern day "lehenga-style sari", worn by Indians across the subcontinent mainly for special occasions, is inspired by the langa voni.
In recent years, however, the langa voni is gaining popularity among girls and young women as occasional wear due to attention in media and fashion.
Once very simple, they can now be seen with extravagant embroidery, mirror or zari work, and bold colors like black and grey which were once considered inauspicious.
Full saris are sometimes woven so that the fabric, when worn, changes color or pattern at the hip, in order to give the visual effect of a langa voni.
