There is a custom of marriage in India, that is, the richer the dowry, the better you can find a good family, which is especially helpful for future marriage. Wearing so many jewels can also show the dowry that one's family can afford more intuitively, and at the same time, I want to marry a good family and live happily in the future. So these Indian women have no money at home, so they have to try their best to buy these jewels and wear them on themselves.
This marriage custom is very different from other countries, so it can be seen that Indians attach great importance to their traditional culture and have higher requirements for women's status in the family, as well as their roles and requirements, so this phenomenon has formed a social trend, which is why it is so common in India.
