Hi Norton29,
Despite some of the negative comments you may hear about the place,Doha is a great place to bring up a family in.
Crime rates are relatively low and life is more family orientated.If you can,get hold of a magazine called Marhaba-it lists all sorts of activities and social clubs etc...There are lots of things to do here,but you have to know where to look!
With regards to dress,I guess you mean in public right?Best advice is to dress modestly,and you should not have any problems.Hope this is of some use to you and good luck with the move....
