What is an illusion gown?

An illusion gown is a formal dress that creates the appearance of having open cutouts that reveal bare skin. In actuality, these cutouts usually feature a layer of sheer fabric. For example, an illusion gown might look as if it were backless but features a sheer tulle panel with tiny hidden buttons.
