If we were talking about what she said then it was great..
but if it was about her outfit.. then yeah it is offensive.. according to Islamic teachings and Qatari traditions... which say an adult muslim woman should cover her hair and wear loose clothes.. and especially for Qatari women..Shela and Abaya are our non replaceable piece of clothing..

So for her, to show up promoting Qatari heritage and culture in an Islamic museum wearing this is quiet offensive...
For I assure you... she wouldn't dare walking around without her abaya..

It's always known that the dark spot in a white thobe would be more eye catching than the white thobe itself.. and that's what these naive girls wearing tight Abayas are...
