In Jonathan Safran Foer's novel "Everything Is Illuminated," the imagery of the sky pulling up its blue dress symbolizes the transition from day to night, highlighting the beauty and wonder of this change. It paints a vivid picture of the evening as an elegant event, suggesting that the night has its own charm and artistry, much like a beautiful gown being revealed gradually. This metaphor encapsulates the magical quality of twilight.

The quote reflects on the delicate relationship between light and darkness, suggesting an underlying narrative of revelation and mystery. As the night emerges, it invites contemplation and a deeper understanding of the world, akin to uncovering layers within a story. Foer’s use of such poetic language emphasizes both the aesthetic appeal and the profound emotions associated with change and transition.
