Anatomy of Costume
Robert Selbie (illustrated by Victor Anbrus) / 1977
Crescent Books / ISBN 0519223686
This has been one of my "go-to" books for a long time. It has beautiful descriptions of both the clothes
and the customs they were worn under (see especially his lovely little offering on 17th century mourning clothes.)
Going through it before planning your costume theme will give you a wealth of new ideas on the times and people.
