I don't honestly believe that anyone in Qatar is going out wearing clothes that they, the wearer, believe to actually be "inappropriate" or not "modest".

It's just that what one person thinks is okay is considered inappropriate by another.

The only way to put an end to this is to tell people how far below their knee their shorts and skirts must reach, or whether or not showing your shoulders, cleavage or elbows is okay.

Telling people to dress "modestly" is like telling people to drive "safely". It means 100 different things to 100 different people.
