Just a couple days ago, I picked up "Make Your Own Dress Patterns", by Adele P. Margolis, at a drama bookstore in the costuming section. The title is a bit misleading, because instead of just dresses what it does is basically teach you how to make any alterations you can possibly imagine from just a basic sloper pattern, for pants and shirts and jackets as well. I've read it cover to cover in a couple days and it looks to be AMAZING and super comprehensive!
