Woven Treasures Gallery Guide - It's a free ebook about Heian costume, in English, by The Textile Museum. It was for an exhibit they had a while back, featuring costumes by the Imperial textile weavers. Downloadable for free from here: http://issuu.com/textile_museum/docs/woventreasures_galleryguide (Yes, it's legal: the Museum itself made the guide and links to it from the exhibit's page.) The ebook has some trivia about uchigi, etc. that I didn't know. And it's FREE. Free!
