Cancan fabric, also known as crinoline, is a stiff, durable textile commonly used for creating structured, voluminous garments. Made primarily from polyester or nylon, this fabric provides body and support, making it ideal for underskirts, petticoats, wedding dresses, flamenco dresses, and costumes that require extra fullness. Its rigid texture allows garments to maintain shape without adding excessive weight, enhancing the silhouette and elegance of formalwear.
