It all began when the Goths started growing up and having to find jobs. They wanted to work in an office (you need a good income to afford all those clothes and CDs after all), but they still wanted to retain their “gothyness.” The result? The creation of “Corporate” or “Corp” Goth. These Goths attempt to find a balance between clothes that are “Goth,” and clothes that conform to the dress code at work.
Your co-worker may be one of these types if they have a liking for dark suits (often vintage or retro style) velvet, hats, brocades, silver jewellery in the shape of spiders/ ankhs/ crosses, and of course, pinstripe (so Tim Burton). You may also find the odd cuddly bat, skull-shaped pencil holder, or other oddity on their desk. Or (dead give away) they might come in on a Monday morning having forgotten to remove their black nail polish from the night before.
The Corp Goth look has become popular throughout the subculture, and has fused with Cyber, Fetish and other Goth styles to become a fashion all of its own. Hence, you will see many Goths sporting pinstripe corsets or velvet suits regardless of their age or occupation.
As for the Corp Goths who do work, their job can almost always be described as “working with computers.”
