Organza is a lightweight, sheer, plain-woven fabric that was originally made from silk.

The material can also be made from synthetic fibers, primarily polyester and nylon. Synthetic fabrics are slightly more durable, but the fabric is very delicate and prone to frays and tears.

Organza is also characterized by very small holes throughout the fabric, which are the spaces between the warp and weft thread in the plain-weave pattern. The quality of organza is defined as the number of holes per inch—more holes indicate better quality Organza.

Organza is extremely popular for wedding gowns and evening wear, as it has a shimmery and translucent quality which creates decadent silhouettes
Transparency.

Organza is a transparent material, meaning you can see through it because the weave creates small holes. The more holes per inch, the higher the quality of the fabric.
Thinness.

The fabric is extremely thin, as the yarns are twisted very tightly before weaving and woven with the intent of creating transparency.
Sheerness.

Organza catches the light beautifully and reflects light rays well. This is a result of the innate quality of silk, as well as the treatment and twists of the fibers before weaving.
Stiffness.

Due to the acid treatment of the yarns before weaving, organza is slightly stiff and is not soft and flowy like traditional silk. However, the wiry feel and structured drape is an asset to designers who want to create sculptural silhouettes.
Breathability.

Organza fabric is very airy and breathable, as the holes in the fabric allow the material to pass air through with ease.
