Kat, dont worry about the dress code, althought Qatar is moslem country but they are some ppl wearing mini skirt, tank-top, sleaveless, bikini at the beach and no one arrested them (YET) hehehe... no really seriously dont worry about the dress code, dress like when you are in your country. Only be cautious with some ppl stare at you wearing some revealing clothes. other than that is cool.

But now you need to wear you warm jacket cos, quiet windy and chilly outside.

Everybody is right and Everybody is wrong, its depend where you stand
