I found this to be one of the most helpful books when it comes to learning how to draw fashion sketches. The illustrations are concise, not to mention lovely, and you can easily figure out the techniques just based on the illustrations.
That's a good thing, because the text is quite flawed. Apparently it's translated into English from Japanese, by someone who either doesn't speak Japanese or doesn't speak English. Don't worry--you'll get what they're saying, but sometimes you have to stop and think about it, because it's phrased in a really odd, roundabout way. Occasionally there are sentences that you just can't quite figure out. Such as this one: "Develop applications by mastering the flow and movement of hair." I get that mastering the flow and movement of hair is important, but what does it mean by "develop applications"? I haven't a clue! Here's another: "Do not compromise when mixing color." Compromise what, exactly? Does it have something to do with values? That would make sense in a very odd sort of way. And one more: "The arms, serving as the core of sleeves, play a key role in accentuating the model's pose." I understand that it's saying the arms are important, but what a way to say it! Betcha didn't know you aren't drawing arms---you are drawing sleeve cores!
All the same, the illustrations are abundant and perfectly clear. Because of this, it really doesn't matter that the text is so quirky. I found it more than adequately teaches the techniques of basic figure drawing, with specifics relating to clothing and accessories. Bonus points: it has sections on drawing patterns (stripes, dots, animal prints, etc.) and a section on rendering different types of fabric, including sheers, knits, denim, tweed, satin, and sequined fabrics. Very helpful! There are tips and tricks, too, that help you make your garments look more realistic.
I'll deduct one star for the flawed text, but the illustrations are so good that it gets an extra star, leaving us with a solid five stars. It's extremely useful for artists and fashion designers alike. I've read several books on how to draw fashion sketches, and this is by far the best. Also try: "Human Anatomy Made Useful" by Christopher Hart. It's a great guide to drawing simplified anatomy, such as for fashion sketches or comic book art.
