The Fashion Sourcebook - 1920s- is a substantial reference book filled with drawings (from period magazines and catalogs) and photos. The book is laid out in chapters: Daywear, Outerwear, Eveningwear, Accessories, Other, and Biographies (although that is only 4 pages of brief paragraphs about the designers). It's all womenswear (no children or menswear in case you were looking for that). There are good essays in front of each section. The pictures are great and each one is on its' own page; some are on two pages but the placement of the picture in relation to the page split is well done. However, I can not give this the full 5 stars because within each section, the photos are not placed in chronological order so it is hard to get any sense of the progression of each type of clothing over the decade. It would have been easy to arrange them by year since each one is on a single or double page. If it had been in order, this book would be perfect. But don't let that stop you from getting this book...it is a terrific reference and the photos and drawings are very clear so it is easy to study each outfit.
