There were lots of cars waiting to take their place in the parade.
These are some of the pearly Kings and Queens of London. The name pearly comes from the pearl buttons from which they decorate their suits. This tradition originated in Victorian times when the costermongers (street fruit sellers) used to have a few buttons sewn down the seam of their trousers. A young man called Henry Croft who had been brought up in a workhouse was fascinated by their flashy clothes and the fact they would all rally round to help fellow 'costers' who were having financial problems. He decided to go one step further and covered the whole of a suit with pearly buttons and then went round collecting money for the orphanage. So the idea of the pearly Kings and Queens was born.
