Organza is a thin, plain weave, sheer fabric traditionally made from silk. Many modern organza’s are woven with synthetic filament fibres such as polyester or nylon. It has an outstanding drape and is often used by tailors to create dresses and skirts with volume. Organza is also a very strong fabric, so do not be tricked by its sheer look. Its cotton variety is called organdy, and it has similar properties to organza.
