Tom Tierney's illustrations cover a 60 year time span when what we would consider "too much", was never enough when it came to embellishing the clothing of a fashionable woman. As eye candy, this is excellent. As a reference, this book is very helpful in establishing the lines and silhouettes of the various decades. As always, the colors are brilliant and the styles are faithfully rendered.
The source of most of these illustrations are famous portraits, magazines of the day, and later photographs of fashionable women. Charles Frederick Worth started the practice of showing clothing on real people, as opposed to miniature costumes worn by fashion dolls, and his work is generously represented, along with a number of other designers, all of whom might have been overlooked by a lesser researcher than Mr. Tierney.
Since there are a multitude of refernces including printed and photographic material that cover the 1890s, I can understand why those fashions would merit an entire book of their own, so I am not troubled by the absence of the decade of the 1890s.
This book serves to provide an excellent overview of how womens' clothing evolved during the Victorian Era all the way up until 1900.
