Books:
Here are some books I recommend that have fantastic information on getting a good fit:
Built By Wendy books. Especially her “Dresses” book goes into nice detail about adjusting fit, making muslins
Colette Sewing Handbook: Also some great info on making muslins and adjusting patterns to fit, including bust adjustment. Her blog, Coletterie, also has a ton of great fit tutorials, and although most are specific to her patterns, many include principles that can be adapted to other women’s patterns as well
Design-it-yourself clothes by Cal Patch – this is a great intro to pattern making, and although it’s really basic (no bust darts, etc), it was really a life-changer for me in terms of understanding the basic dimensions of a pattern and how to manipulate them.
