It's best to use the materials listed in the pattern tutorial, but if they're not available at your local fabric store, feel free to substitute! Here are some of the more commonly used fabrics in garment construction. Cotton Voile: A lightweight, sheer, and airy fabric that drapes softly. It is perfect for creating flowy and breathable layered dresses due to its translucence. Cotton Lawn: A lightweight, finely woven fabric that is smooth yet durable enough to give some structure to the dress. Rayon Challis:  A lightweight woven fabric with a silk-like lavish feel to it. It works well for creating comfortable casual or bohemian-style dresses. Knit Fabrics: A comfy and stretchable textile. It's great for body-hugging dresses that form your shape or casual wear, such as maxi dresses! Double Gauze: Double gauze consists of two layers of thin, gauzy fabric lightly tacked together. It's soft and great for relaxed dresses on summer days. Chiffon: A sheer and lightweight fabric, chiffon is often used for flowy and ethereal gowns, particularly for eveningwear and special occasions. Satin: It's a soft drapey fabric with a shimmery surface, making it a great choice for formal dress patterns. Silk: Known for its luxurious feel and lustrous appearance, silk drapes beautifully and adds a touch of sophistication to any design. It's perfect for prom dress patterns or bridesmaid dress patterns!
