Organza is a sheer, lightweight, and crisp fabric that is known for its delicate appearance and elegant drape. 

It is typically made from silk or a synthetic fiber like nylon or polyester. 

The fabric has a smooth surface and is woven in a plain weave, with thin and transparent threads. 

Organza is often used in formal attire such as wedding dresses, evening gowns, and cocktail dresses due to its ethereal quality.

It can also be used in decorative applications like drapery, tablecloths, and gift wrapping. 

Organza fabric can be dyed to a wide range of colors and may also be embroidered or embellished with beads or sequins to add further elegance to the fabric.
