I received "Blueprints of Fashion, Home Sewing Patterns of the 1940's" as a gift during my trip, and am really enjoying it! I highly recommend both this book and the 1950's version to sewists, vintage clothing aficionados, and anyone interested in fashion design. They are excellent compilations of the fashions of the day, would provide wonderful inspiration for your own sewing projects, and work perfectly as pictorial references for dating vintage clothing. Have you perused either of these books? Please share, I would love to hear!
