I absolutely love this book. I bought it earlier today and have been devouring it. It breaks down various styles from the 20th Century, such as Ingenue (Audrey Hepburn); Goddess (Marylin Monroe) and Ice Princess (Grace Kelly), giving you a background to the style, including notable designers and modern takes; how to achieve aspects of the make up; and what to look out for in vintage shops.
It's a great introduction to Vintage fashion, but it might be a little basic if you already have a lot of knowledge of the subject.
