Here is a link to amazon.com where you can preview this book http://www.amazon.com/Create-Perfect-Fit-Measuring-Solutions/dp/1440239614/ref=sr_1_1?ie=UTF8&qid=1414623882&sr=8-1&keywords=create+the+perfect+fit+joi+mahon
I have read this book from cover to cover but not actually tried it out yet. I have also taken both of Joi's classes at craftsy.com http://www.craftsy.com/instructors/joi-mahon
The first class, Fast Track Fitting comes with the Vogue fitting pattern and is followed up with Fast Track Fitting in the Details. She is not particular about what size pattern you start with so this method works if you have a vintage pattern that's way too small or the closest size range was sold out when you bought a pattern so you bought the larger range.
Joi teaches a method of fitting which I've not seen elsewhere and which seems to me, at least, to be very logical. It involves measuring small areas of a pattern and the corresponding areas of the body. Initially you make flat pattern adjustments without reference to any other pattern pieces or area in the pattern piece. If you need to add hip circumference, is it logical to add it equally to each quadrant of the lower body? Perhaps it is for some bodies but for others, the extra is needed in the seat or the tummy so that's where you add it. Most people have figured out by now that if you're bigger than a B cup, you need to increase the front pattern piece(s) only -- not the back [but you will still see instructions for adding the increase equally at the side seams]. I'm interested to try her solution for full busts which is based on dividing the bust area into 4 quadrants and adjusting each of these. The divisions she makes on the garment/body/pattern appear to be similar to those used for grading patterns. They are also similar to the horizontal and vertical balance lines that you might mark on a muslin.
Once you've altered the pattern based on a comparison of your measurements with those of the pattern, a muslin is essential to refine the process because in the end, you do have to make the pattern pieces sew together. There are a couple of adjustments I've not seen before including one for lymphedema in the arm.
