I've studied and drawn fashion illustrations for more than 20 years. I'm familier with the history, the artists, and the techniques of this genre.
Most fashion illustrations serve the purpose of either selling clothes or giving directions to people actually making the garments. Short of that, they've been used to present a fashionable illusion for p.r.
I'm not sure what purpose of the often very abstract illustrations in this book are supposed to serve. They aren't glamorous. They aren't drawn well enough to sell or direct in the creation of garments. Perhaps they were intended as decorative illustrations at either point-of-purchase locations or on websites.
Either way, I found the enclosed illustrations lacking in imagination, verve, and technical skill. This is the first book I've ever returned to Amazon.
