Sorry about hearing that,,

But be aware that not everyone who wear Qatar traditional clothes (even Dishdasha or Thoob or Abaya) is Qatari. There are some Indians and Pakistanis men and women who wear Thoob and Abaya. Also some Arabic ppl (Jordan, Iraqies, Palestinians , Egyptians) wear Thoob and Abaya. In the other hand, there is no country in the world that is safe at night, so avoid walking after 11 pm =)
