It's Patterns of Fashion; doesn't get much better than this. No detailed construction tips, but this is in the period where dressmaking guides were widely published (and accessible open source online now). Some of the later-date dress patterns are quite dense on the page, but that's more due to the complexity of the patterns than any fault of the author.I would also say the dresses here are a bit more "specific" in taste than those in PoF1, which seem to be more representative of their periods. However, it's easy to adapt a bodice or skirt pattern to your specific taste, and this book contains many of those. I also personally like the period pattern and cutting guides in the front. Lifted directly from period magazines and patterns, these double the number of patterns and styles you get with the book, if you are willing to scale them yourself.
