Rahat's explanation aside, to me it still seems like poor business practice if you are comfortable with the design company you hired using images to promote your product that you know are NOT of your product (even if they are legitimately obtained, licensed images.)

To be fair, however, this is not something that only Pakistani Highland dress companies are guilty of. Only this morning I came across a US kilt retailer guilty of the same thing. On their web site, on their catalog page selling Strathmore's 11 oz Irish family tartans, the only product photo they show is one of Lochcarron's models wearing a tweed casual kilt from several years ago. I recognized the Lochcarron stock photo immediately. There is not a single image of Strathmore's tartans, or any kilt made from their tartans, on the site.

I truly don't understand the willingness some people have to advertise their products with images which are clearly not of their product.
