I've been wearing my curent pair of jeans for about 2 to 3 years on some quite prestigous golf courses. Of course, because they are brown, nobody has noticed.
Makes a mockery of the whole idea.
It doesn't make a mockery of the whole idea because the whole idea is that jeans are banned because, in general, they look scruffy. Your jeans that you wear probably don't look scruffy (I'm assuming) and so no one would probably even notice that they are jeans.
They could write in the dress codes that "scruffy looking trousers" are banned but that leaves it open to interpretation... banning all jeans just makes the dress code unambiguous and easy to understand and adhere to. Well, for most people anyways...
