I confess, I was extremely disappointed in this book, especially considering its relatively high price.
I'm not sure exactly who the book is aimed at. There is very little helpful content at all.
The first 26 pages -- which sounds like a lot, but isn't, considering the format -- consist of a few figure drawings plus a few notes about body and facial proportion, a short, generic section on art materials and techniques, a basic colour chart, etc. Nothing specific to the topic of drawing the costumed figure, at least nothing specific enough to be any use; there is nothing here to help the would-be artist achieve a finished result. Then follow 3 pages of PhotoShop instruction, or rather an extremely lightweight overview as to what PhotoShop can do.
Then comes the body of the book. This chooses various periods, such as "Cavalier 1620-1660," "Restoration 1660-1680," "Baroque 1680-1715" then gives a half-page of overview, including one or two sketches of things like a hat, a pair of shoes, maybe a dress or two, one large black and white drawing on the facing page. Only six full costumes (3 male, 3 female) for a relatively modern era covering a 100-year time span?
The closer we get to our own times, the less satisfactory this pitiful 'overview' becomes. For example, the female 1940s page drawings include 2 shoes, two hats, two hairstyles, one small drawing of a coat and one large drawing of a woman in a two-piece suit. That's it for the entire decade!
These costumes are nearly all designed for the wealthy classes, virtually nothing of everyday wear for ordinary folk. Giving the reader only one detailed example per period is extremely unsatisfactory. There really isn't any reason to buy this book that I know of. There isn't enough art instruction included to make an artist, and there certainly aren't enough costume examples to satisfy someone interested in either period costume illustration OR theatrical costuming.
If this had been a children's book (which it rather resembles, once you get into it) which only cost a couple of pounds, I wouldn't be complaining. However, I wouldn't have ordered it either. For this price, I expected a lot more.
