I picked up this book and read it from beginning to end. I found the facts to be very interesting. Particularly of interest to me was the information regarding sizing of patterns and ready to wear. This book also offered many alterations. I would refer to these in addition to alteration methods in other books (Fitting and Pattern Alteration or Fabulous Fit, for example). I would recommend this book for beginner or advanced dressmakers. The photos and step by step alterations were wonderful. Included, also, were people of many sizes, variances, and ages. One of the best examples of why we sew was the fitting example of Martha's jacket. The book showed Martha wearing an altered size 12 pattern. It also showed her wearing jackets in similar styles in various price ranges and from various stores. The altered size 12 was the best fitting and most flattering by far. It outshone even those designer jackets costing hundreds of dollars. This book also showed how two people of the same height and weight would require vastly different alterations because of their weight and height distribution. Some people are short from waist to neck (me). Others are long in this area. Some have short legs but not short torsos. It is important, the book stressed, to know yourself and your body. They showed how to make a body map. I wasted no time at all doing this. I have a fitted sloper and know what alterations I need to do on my own garments (high right hip, wide waist, full bust). These were things (especially the high hip) which I never really saw until I made the map. When we were done with this process, we stood back and looked. The high right hip (and some other things) were actually noticeable. I would highly recommend this book as an addition to any sewer's library. The information is invaluable and timeless and PRACTICAL! I would also recommend READING THIS BOOK!
