And how it is reflected in the novel
The title "First Impressions" was the original title of the now famous "Pride and Prejudice". Austen wrote "First Impressions" between 1797 and 1798. Approximately ten years later, she changed the title to "Pride and Prejudice". However, both titles are greatly reflected throughout the novel. Below are some examples of how the title "First Impressions" is reflected in the novel.
