In this case, you just need a professional photographer instead of getting to arrange a professional model like the latter. With the photographer and a good setup for background, you can click good looking images of your saree. Make sure it covers all the design on the saree.
If the design is not repetitive you can fold the saree and keep it in front of a good background and then have the photo click. Make sure the aim is to display all the design that is there, so we do not miss its selling point.
Very interesting and useful
