Carly is Sue's best friend. She began in season 1 as a geeky character, wearing glasses and braces. Her braces were removed mid-Season 1, and she became more popular as a result, Sue seems to be jealous, if only subconsciously, and wears makeup which her family finds garish. From Season 2 onwards, Carly has since reverted back to a more geeky look. However, her friendship with Sue remained strong despite Carly's makeover. In season 3, she donned her old outfit, once again wearing braces and glasses.
