Madam Malkin's Robes for All Occasions

Madam Malkin herself, a short, cheerful witch clad entirely in mauve, stands customers on stools and pins long robes to length. On Harry's first visit a pale boy with a pointed face is being fitted beside him and boasts that he will bully his father into buying him a racing broom. Before his third year Harry comes back for new robes, the old ones now inches too short, and the shop takes out a newspaper advertisement for a sale.
