A double-layer drape includes an upper beam and a window curtain connected to the upper beam. The window curtain includes an inner layer and an outward layer. Both layers are formed with different shade cloths. The outward layer is a pervious-to-light curtain. The inner layer includes a plurality of opaque curtains. The inner layer curtains are connected to the pervious-to-light curtain by up-and-down overlapping. In addition, the opaque curtains are simultaneously folded upwards or hung over downwards through pulling operating cords by a user to achieve the indoor anti-dazzling or semi-opaque effects.
