Part of the art of a designer is to know how far he or she can push the changes without over-reaching and bursting the bubble.
No matter whether it is new clothing at a fashion show or designer shoes or even a new shaped toaster, there has to be enough people convinced of the idea to produce and market it.
Now and again there is an occasion when the designer can really let the creative juices go and no more so than Ladies Day at Ascot. This is the day when women wear hats designed presumably by asylum dwellers on acid.
Astonishing creations are on display and this seems unfair to the horses that look very ill at ease with each passing creation.
Needless to say, there is rarely a rush the next morning by women up and down the country wanting to buy that hat they saw on television from Ascot.
But these hat designers are not as daft as we think because the more outrageous the hat the more likely the camera is to find them and this always gets the designers name mentioned. Free advertising like that is hard to come by and one particular designer seems to manage a mention every year.
By the very nature of their work it is almost impossible to find a modest designer of clothes or shoes. If you are not flamboyant it is unlikely you are a designer. These creative types crave attention and praise so their designs have to be bold and adventurous to get this attention.
Sometimes it seems a little like the Emperors Clothes story with some designers who become so idolised that it seems they can produce any old rubbish and receive praise.
