I kept this one a bit undertrained so you can poke around with it, at it's core it's an asymmetrical evening gown/prom dress with a flattering silhouette and attached on-side cape/cloak. Its probably Satin or a synthetic fabric, so it'll resonate better with shiny things.
See examples for how to riff with this:
TL:DR - Str 0.7-0.8 (warning "cleavage" might destroy the top)
Default - long dress, bare arms
cape to add cape
the greatest hits, latex, crushed velvet, satin, etc
