Organdy is a balanced plain weave.[2] Because of its stiffness and fiber content, it is very prone to wrinkling. Organza is the filament yarn counterpart to organdy.

Its sheerness and crispness are the result of an acid finish on greige (unbleached or grey/beige) lawn goods.
It comes in three types of finishes: "Stiff" is most commonly used, but "Semi stiff" and "Soft" finishes are also available. The latter two finishes are more popular for summer wear and drapey apparel whereas the first one is more popular for loose apparel and home textiles such as dresses and curtains.
