I have been sewing for over 50 years. The one thing that always bugged me over the years was pattern fitting. I soon found out that I was not a standard fit when the bodices of dresses did not meet across the chest and the front waistlines were up around my ribcage. I had a larger than a b cup bra. It wasn't until recent years that I was told that patterns were only drafted for b cup bras. Over the years, by observing patterns and body shapes, reading books, (not many available years ago) and eventually learning the art of pattern drafting, I learned the art of pattern fitting and alteration. I have always been interested in fitting. Many books have become available in recent years on pattern alteration but I have not found one that addresses problems in the same way that this book does. So many books simplify one problem and do not let you see how the alterations affect other seams. This book goes through the whole process. It is the most comprehensive book on the market today. It starts with body types, how to measure, why you should alter and how to alter the pattern. I do not need a lot of the book's information today. However, it has been a confirmation of all I have thought of throughout the past years. I have purchased the book to add to my collection and I am thoroughly enjoying it. If only it had been available to me over the years, I would not have felt so stupid because patterns did not fit me. I would have had all the information in one place rather than the thinking and reading I had to do.The section on mature and maturing bodies is wonderful and this is one area I will be visiting. Congratulations to the authors for a fantastic book. The book in fun to read. It has lots and lots of pictures of REAL people not drawings. The illustrations of the pattern alterations are excellent. It is many books rolled into one and very good value. Reading it has sparked me off to want to start to sew again after too long an absence.
