Elle Editor-in-Chief Nina Garcia has penned four books on fashion and style, including my favorite, The One Hundred: A Guide to the Pieces Every Stylish Woman Must Own. This book is a must-have if you love fashion or are just looking to add some style into your busy life. In addition to detailing the 100 pieces every woman, no matter her age, should have, the Project Runway judge also includes tidbits of fashion history, fun quotes and insider tips. The silver book also features the stunning fashion illustrations of Ruben Toledo. While you can obviously click to buy on Amazon, try browsing through resale bookstores like Bookman’s too as it was published in 2008.
