Bernie

Bernie was a boy with floppy blond hair, that Dirty Bertie was mistaken for in the story Fashion.

History
Bertie had gotten lost while shopping for shoes at a department store with his mother. He ran into Laura, who had been expecting a boy model named Bernie and asked Bertie if that was his name. When he corrected her, she thought it was a printing error and made him up for the fashion show. When the real Bernie showed up late, Bertie skateboarded away.
