Nancy is determined to make the cover of her very first book report as fancy as she can, but she spends so much time on it that she has no time to write about the book.
Nancy writes a report for school about her great-grandfather, making things up so he seems less ordinary, but when she learns that Grandpa will be there to hear her read the report aloud she realizes she was dishonest.
Preparing for picture day at school by choosing just the right outfit, Nancy wonders how she should style her hair and considers pigtails, a bun, and long ringlets before formulating a plan that has her reaching for the scissors.
Nancy, who likes to use fancy words, is excited to wear her elegant nightgown for Pajama Day at school, until best friend Bree and Clara impress everyone by wearing matching pink polka-dot pajamas.
