According to Part 1 of Kenneth D. King’s Smart-Fitting Series, the key to making a garment that fits perfectly is understanding three basic principles. Every fitting process begins with evaluating how the body fills a garment. Understanding how to fit your garment involves understanding that there are three possible fit-problem scenarios: an area is too large, an area is too small, or an area isn’t shaped right. In Threads issue #147, Kenneth explains the principles of net loss, net gain, and no net change. Once you get a feel for it, you’ll find this method of fitting patterns an uncomplicated and versatile way to achieve a perfect custom fit that looks like it was draped to your body.
