I have a few sewing books, one from Reader's Digest and another from Vogue Sewing. Although they're good for what they do, I'm looking for something with more advanced things like draping and tailoring. These all-in-one guides tend to be repetitive, dated, and generally limited. Hell, a lot of the Reader's Digest one is about sewing pillowcases and drapes.

TL:DR- What's a good technical book for draping, tailoring, or similar subjects?
