Well actually saris are most commonly worn in the Southern part of India. In the North its salwar kameez. Saris in the North are sometimes worn on occasions or festivals.
These days it's a mixture of traditional wear and western wear.
Have you tried wearing saris? Is this attire affordable?
Saris come in all sorts of material and can cost from a few hundred rupees to a few hundred thousand. those saris that have manual embroidery work normally cost a lot but it also depends where you buy them from.
Saris are affordable but the problem is wearing them and keeping it on while outside. It takes some practice.
