Busts come in all different shapes and sizes, and your pattern should work with your body, not the other way around. Body-positive sewing expert Jenny Rushmore helps you conquer a successful full bust adjustment (FBA) — the most common fitting challenge — and confidently work with any type of pattern. Understand what types of patterns need an FBA and how to approach the FBA for styles with single bust darts, bust and waist darts, no darts, princess seams and more. Learn how to refine post-FBA dart placement and manage extra-large FBAs. With Jenny’s step-by-step guidance, you’ll master the FBA for any style and cup size to perfectly fit your natural curves.
