What type of fabric is a plain woven material that is fine, sheer, and often used for dresses?

The correct choice is organdy, which is known for being a lightweight and sheer fabric. Organdy is a type of plain woven material that has a crisp finish and is often used in the creation of dresses, especially for special occasions such as weddings and formal events. Its delicate nature allows it to drape beautifully while maintaining a certain structure, which is essential for certain styles of dresses. The transparency of organdy adds an elegant touch to garments, making it particularly desirable for layered outfits or overlays.

In contrast, satin is a smooth and luxurious fabric with a high sheen, commonly used in evening wear and formal attire but is not sheer. Tulle is also lightweight and sheer but is typically stiffer and more net-like, often used in veils and petticoats rather than the main body of a dress. Linen is a thicker, more textured fabric known for its breathability and is mainly used for casual or summer clothing, lacking the sheer quality that organdy offers.
