In the book, they usually have on the left-hand page, a model wearing clothes which are to be avoided, and on the right-hand page is a picture of a model wearing better clothes. Accompanying the photographs are explanations of particular items of interest about the ensembles, as well as a paragraph describing 'What this outfit says about you.'
These ladies do have some good advice about clothing and what it says about you. However, a lot of their photographs were heavily dependent on the model's hairstyle, facial expression, and posture to convey an impression, more than on her clothing.
Additionally, most of the clothing to be encouraged was designed solely for women who are 5'10" and weigh about 120 lbs. The style favored the most by these women was bell-bottom slacks worn under a knee-length frock coat or dress.
I am 5'0" and weigh more than I used to. I'm not fat, but I am gaining weight. Even if I still weighed 90 lbs., I couldn't possibly wear most of the suggested styles. I like frock coats, but on a woman of my height, they look dowdy and ridiculous.
So, while I think these ladies had some good ideas, their book is largely useless to me, because it espouses a clothing style I can't wear. Most women who consult such books for advice on what to wear are not built like models. Most women in the world, period, are not built like models.
When do we get a 'how to dress' book that is written for the rest of us?
