The idea for the book came six years ago: She wanted it to be a “bible” for getting dressed. “Clothes should never be intimidating, they should always make you feel good about yourself,” she tells Refinery29. “I wanted everyone to understand what they want to wear, how they want to wear it and where they want to wear it.” In the book, Barron shares item-by-item tips for every kind of occasion, from heading to the office to going on a first date (which obviously differs from the second and third one). “The thing to remember about making use of everything in your wardrobe is that you don’t have to love everything all the time, and instead you have to know what you will love again in future, so you don’t part with it and regret it later,” Barron says.
