Importance of bangles for married woman :

Wearing bangles, especially lac, glass and shell are a must for married woman. However, the material and color varies from region to region. While in north India mostly Punjab, Jammu & Kashmir and Rajasthan, the ivory bangles (chuda) are compulsory; in states like Odisha and West Bengal, bangles made of lac (pola) and shell (Shankha) are mandatory for married ladies.

Bangle is the symbol of marriage. In some parts of India, while changing bangles, women never allow their arms to be completely bar, instead they will wrap their pola around their arms while wearing the new set. Bangles are not for widows in Hindu customs. They can however wear gold bangles, but glass bangles are a strict no-no for them.
