Custom Swimwear is the sixth title in Marie Porter's Spandex Simplified series, and is all about designing and creating flattering, comfortable, and durable swimwear.

This sewing manual is written from the experience of not only a spandex designer, but a former "performance" athlete. Written in layman terms, Custom Swimwear features carefully explained, step-by-step instructions and more than 250 full colour photos and diagrams. Requiring only basic sewing knowledge to get started, beginner and advanced seamstresses alike can enjoy using this book... and produce spectacular results from it. Learn how to design swimsuits that flatter any body type and how to alter patterns for shape, size, and style. Learn the tips, tricks, and techniques to make many of the design elements that can be used to design and create almost any style of swimsuit imaginable! Please note: As spandex patterning and sewing techniques are largely the same across many styles of costuming, a large portion of each Sewing with Spandex title is the same/similar to the other Sewing with Spandex titles.
