The book "encyclopedic" reviews (AZ) all types of clothing and garment parts (collar, buttonholes, belts), accessories, and appropriate terms to designate them. A didactic purposes, it is richly illustrated. I just regret that there is not (as I expected) more practical passages, I would have liked some thumbnails bosses for example ... When we are presented with a type of handle, why do not accompany the boss? In short, this is informative terminology issue, but if you want to perfect sewing, this is not the book to buy, the practical aspects are not developed.
