Carl Köhler (1825–1876)

This is a good resource for costumers; filled with authentic pieces found throughout history, and well referenced.

This book was originally published in the early 20th. Some of Kohler's ideas are now considered inaccurate, including the clothing patterns he created. Nonetheless, it is a useful book, as long as one augments it with other, more recent studies.

Personally, not that great. I rather use something like Costume in Detail, or 1000 Years of Fashion, if you can find it.

In this reference, a costumer can use the point-projection system to recreate the historic pieces.
