I've organized the book (out April 3rd!) by seven archetypes of tomboy style: The Sophisticate, The Prep, The Naturalist, The Rebel, The Girl Next Door, The Jock and The Adventuress. Lately, this subject has been coming up a lot in conversation or out at dinner—people ask the questions: Which one are you? and Which one am I? It's fun to think about! I'd love to know, which archetype are you? Are you a mix of a few? Which one do you want to be more like?
