black ... Black ... Black
If you don't look like you've just pulled yourself out of a coal mine, you're doing it wrong!!! Heave, heavy eyeliner. Make it look as if you've had both of your eye's bashed in ( forcing some people to beleive that someone had already beaten them to it). All silver jewellery ("Gold! Are you mad! You know those pesky werewolves!") Heavy on the ankh, spider and bat motifs.
For a more exhaustive guide to what's in or out for goths you can but refer to Helle or just head straight for the sterotypes available interchangably in both female and male versions.
