Creating well-fitting lingerie and swimwear can feel intimidating due to stretchy fabrics, precise measurements, and specialized hardware. This course simplifies the entire process, guiding you from basic textile concepts to finished garments. You will transition from understanding basic sewing terminology to confidently drafting patterns and constructing your own custom-fit bralettes, briefs, and swimwear.
Through clear written explanations, you will learn how to work with delicate laces, high-stretch Lycra, and essential elastics using a standard home sewing machine. The curriculum also covers modern fabric technologies, including sustainable recycled nylons and chlorine-resistant spandex, ensuring your creations are both durable and contemporary.
What you'll learn:
- Understand the foundational properties of stretch fabrics, elastics, and specialized lingerie hardware.
- Draft custom patterns for basic briefs, bralettes, and one-piece swimwear based on individual body measurements.

- Master professional finishing methods, including inserting underwires, attaching elastics, and lining swimwear.
- Adjust patterns for inclusive sizing and custom fit modifications to ensure comfort and support.
- Select sustainable, modern performance fabrics that offer durability, chlorine resistance, and shape retention.
The course begins with essential terminology, tool overviews, and fabric mechanics before moving into step-by-step drafting guides and written construction walkthroughs. You will practice your skills through structured design exercises and detailed sewing instructions.
This course is designed entirely for beginners, and no prior experience in pattern drafting or specialized sewing machinery is required.
