I bought this book after obsessing over it for a couple days. The pictures, as have been mentioned in other reviews, are utterly gorgeous. But beyond that this is kind of a waste of money.
I wish this book didn't masquerade as a style manual as it's really all about Brooks, her journey through fashion and (as she makes quite clear) her very privileged position in the fashion world via her (very, VERY rich) familial background. Seriously, I laughed out loud when she claimed proudly that a $300 silk tank top is totally worth it because it lasts over a year. Her "thrifty" section just feels like a weak attempt to relate to us regular fashion-loving folks, and her idea of high-low mix in fashion feels more like her throwing a bone to people who can't happily splurge on $1000 pieces she got her hands on because a designer used her as a muse. I'm the last person to judge on spending exorbitant amounts of money on expensive clothing, but to present it as an everyday and perhaps NECESSARY thing for fashion lovers is kind of ridiculous.
And because it's all about her personal style, the sections are really quite limited to her personal experience. She clearly did very little, if any, research into the styles she talks about and she presents them as the end-all, be-all of acceptable style.
This book is a thinly veiled fashion autobiography, NOT a style guide, with some of the most absurd and useless style advice I've heard outside of Vogue and Elle. But hey, the pictures are lovely, as is the overall layout and design of the book. Although Brooks probably had little to do with cultivating either.
