I’m not sure how well-researched this book is. It made a few statements that set off my warning bells. For example: In explaining the term ‘barbarian,’ she says “[t]his name was given to them by the Romans because of the fierce and loyal way in which they fought in battle.” I had always been under the impression that the name was given to them because their language sounded like “barrbarr” to the Romans. Details like this made the history sections questionable, but, knowing very little about clothing, there isn’t much I can say about those sections. however, I would recommend using this as a source of inspiration rather than as primary research.
The illustrations were inconsistent. Some were sketches, some pictures of art or statues, and they didn’t always make it clear what parts of the costume we were meant to notice. I found explanations rather lacking as well, often having only a vague sense of what the costume piece would have looked like or what the term referred to. Different sections (17-20th centuries, for example) received far more coverage than other sections.
All in all, I was fairly disappointed. As research, I found the book questionable. In terms of inspiration, I found the images lacking. Read en masse with the other books I’ve gone through, it works fine. It filled in a couple cracks, gave me a few more decent pictures to work from, and so forth. But I wouldn’t recommend it to read alone or as a primary source of research/inspiration.
