One of the biggest influences on Gothic fashion has been the imagery in Gothic literature and their movie counterparts, particular that of Victorian writers such as Edgar Allen Poe and Bram Stoker. Victorian fashions like corsets, lace, frock coats and pale skin are popular throughout the scene, but maybe none wear them with as much style as the Victorian Goth.
Like their Victorian role models, the Victorian Goths wish to convey an image of decorum and dignity. Clothes must be smart and, for many, historically accurate (corsets are to be worn beneath one’s garments, of course). Ball dress and mourning garb are particularly prominent in the scene.
Victorian Goths may also indulge in activities that were popular in Victorian high society, including theatre, masquerades, tea parties and poetry. And, naturally, any kind of Dickensian or other Victorian festival that gives them an excuse to parade around in costume (not that they need an excuse).
As for music, opera and classical are the true Victorian Gothic genres, but Victorian-inspired bands such as Rasputina are also acceptable.
