You aid in your post that "...I believe it is important what is INSIDE a person, not what is on the outside..."

While I could'nt agree more with u on the first part, I still believe that it is also important for a person that both his inside and outside are in sync.

"....what about women who dress as per the islamic values HERE, and then change once they leave for vacation?..."

muslim women are expected to wear hijab to obey Allah's command which is mentioned in the religious texts.

If some women wear hijab for other reasons then it is for them to answer to Allah in the hereafter.

And, I think this should be one of the focal points in this campaign to encourage women to make them understand the reasons why modest dressing has been prescribed by our creator and also to highlight the ill effects of immodest dressing in the society (rather than just focussing on Qatari values and culture )
