Once upon a time (but not too long ago), girls only wore dresses.
And only boys wore pants.
Until one day, a young girl named Mary had an idea, and it was kind of a big deal.
Inspired by the true story of Mary Edwards Walker, a trailblazing doctor who was arrested many times for wearing pants, this fresh, charming picture book encourages readers to think for themselves while gently challenging gender and societal norms.
