I ordered this book in CD format directly from Bra Maker's Supply, Beverly Johnson's own company. The cost of the CD is nearly half that of the printed manual. I printed out the pages and placed them in the binder. So basically I saved $40 just by doing a little bit of work on my end. You could probably do it at a copy shop (along with your proof of purchase) for a small fee if you don't have a good home printer or if you wanted to have it coil bound. The photos at the end did eat up a bit of ink but are worth it in my opinion.
This book does a really good job of helping you ascertain good fit for a bra with more than enough information for the home sewist. It also has copious amount of information on various fit and tweaking issues. The construction sections are similar to the pattern instructions I received with the Classic Bra pattern but more thorough. Perhaps one of the funniest parts of this book is a checklist of things NOT to do when sewing a bra.
Ostensibly, someone with good sewing and drafting skills could use the information in this book to alter a Pin Up Girls classic bra into several styles of bras, thus saving $20 a pop on future patterns. I'm not sure if I'm that skilled yet, but it is good to know.
