Milkman's Daughter 

When a female and her siblings are compared and she looks nothing like any of them, she is said to be the milkman's daughter insinuating her mother had an affair with the milkman and she was the resulting offspring.

Cindy is tall and blonde and her sisters are average and brunette, so she must be the milkman's daughter.
