"The women dressed wonderfully well. Most of them were in dresses made of elastic crystal in different shades; some of them seemed to flicker with all the colours of the rainbow and in others, had metallic crystals or rare plants, butterflies and shiny beetles fused into them. One of the fashionable ladies had live fireflies festooned around her skirts which produced a dazzling flash as she moved around the dark avenues of trees. A dress like that costs a lot of money, people said, and can only be worn once because the insects quickly die."
