You can wear what you like Frank, but my own feeling is, that if you are going to spend time on the presentation of your dog, then you should be willing to complete the picture and at least be smartly turned out yourself. The best ones to look at are the junior handlers.
You will find though, that it varies from breed to breed, the standard of exhibitor attire. In my breed it's very smart, and in some others it's very casual. I would never advocate jeans though.
