Indian outfit for an American musical?

This last two months I have been busy at work rehearsing the musical which with my colleagues we are going to present during the Annual dinner. It is a famous American musical that we adapted in a bilingual version (English and Chinese-Cantonese) with the guide/direction of a producer from TVB and a dancing teacher.

When it came to discuss the costumes, we tried on some that looked all right but the producer did not seem really satisfied with them. The day after he came back with some sketches of each one of the characters and I noticed that I was the only character he draw with a long princess dress. Also he told that it would be really beautiful and original to dress all the girls up in punjabi which is the common Indian (but also traditional Chinese) female outfit. Let’s see which will be the final decision!
