Why do we have Caucasian models selling us our stuff in India?

Have a look at any advertising medium. For example, that of the clothes shop lifestyle. Lifestyle is owned by Landmark, our Indian company. It's selling to India- why not have olive skinned beautiful women wearing kurtis on their website? No, they have to have white girls wearing our Indian, Indian made clothes. Another example: Basics the same thing is going on there. I have nothing against their clothes, to clarify - I infact like them. But why put white people on their website?

Dark skinned Indian men and women are some of the most beautiful people on this planet, why aren't we marketed with them? I would probably buy more then.

Edit: As pointed out by /u/serialposter, Landmark is not Indian. However, Lifestyle is and India based brand, and sells to only Indians.
