Lady Spookyraven's finest gown
This dusty remnant is all that's left of what was once the most elegant, most expensive gown in Lady Spookyraven's wardrobe. It's a poignant reminder of the transience of all things. Womens' clothing in general, I mean. This dress was probably out of fashion a week after it was made, never mind decades later.
