Jaina's Winterveil Gown
Bright Lady Jaina
The gown Jaina Proudmoore wore as described in Christie Golden's Arthas: Rise of the Lich King during the Winterveil feast with Arthas. The book describes her as dressed all in silvery white with her golden hair making her look like a white candle. Just something based on that description, wasn't sure if it still belonged in Cosplay but since it's Jaina and the outfit is established in the EU, I figured it went here. Ref image is Jaina's general appearance, not this particular outfit.
