I read the book (thanks Alexandra!) and I think it's easier to understand than Kibbe. Mind you, the section on your "archetype" is no easier to understand, so if you couldn't figure out your type in Kibbe, you'll be no further ahead with this book.
However, I really like the section in using Pinterest to hone your style, and the book is laid out as a few exercises which are good...if you actually take the time to do them.
The section on colours sort of leaves you hanging. Basically tells you to go get a professional opinion about your colours. But if you already know your colours (which i think you do, BC) then you can ignore this chapter.
I had a day off the other day and really felt like I made some progress around where I want to go with my style in 2017 thanks to this book.
There's an emphasis on pictures at first, to give you a visual idea of what you like. It then tells you to find parallels between your pictures and write them down. These are you "desires". It's basically what you really like.
It also talks about your goals (ie: what activities and events do you need clothes for and also, what impression you want to give while doing those activities).
And it then asks you to try and marry your activities with some of your desire words AND your archetype. This part is a bit tricky because sometimes your desire words don't line up with your activities or archetype, and so you might need to adapt your desire words or throw them out.
I like that the book was task-oriented.
As Beth Ann says, a nice light read if you don't do the exercises.
