I have always wondered why women, specially in India wear shawls on their shoulders. Unlike, in western fashion, in India almost majority of the women do this in winter. Why not wear some warm woolen and fashionable full sleeves sweaters?

Yes.

As your question itself clearly tells that shawls give an enhanced look to womens beauty. Wearing shawls gives not only enchanting look but it is a traditional wearing and being used since very long time in India. Further, it is also worn by mens to keep their body warm during the winter. However, it is not for fashion purpose.

Hence, there are many shawls suppliers, exporters and shoppers that deals in all kinds of shawls.
