an instance where something can be familiar, yet foreign at the same time, resulting in a feeling of it being uncomfortably strange or uncomfortably familiar.
Corsets do this to some degree. Yes--she looks like a woman, but something seems slightly off. Even a basic corset is uncanny. Oh, her waist is exaggerated. "Cool! I love it!" says the dark fashion fan, who enjoys the uncanny more than most. But then you get to the more extreme corsetry, which becomes a form of body modification. Beautiful? If you like the uncanny, yes. If you're terrified of something appearing human and not at the same time, then probably not.
When we talk about how "hardcore" someone is, we could be talking about where in the Uncanny Valley this person stands....literally:
|normal feet looking normal: not uncanny, unless you've never seen anyone wear shoes|
|Unless you're ok with your uncanny side, you might be creeped out by this.|
Not everything in dark fashion is uncanny. Most of it isn't. Here's an example for nails (you knows I loves my nails):
|dark fashion design : NOT uncanny|
|dark fashion symbols/icons/signifiers : NOT uncanny|
|literal interpretation of horror theme (zombie nails). gore is scary, but not (superficially, at least) uncanny|
|dark fashion-forward colors and shape: NOT uncanny|
What's this uncanny valley I keep talking about? It's an actual theory, though i've applied it to fashion. The original definition, from the wikipedia: The uncanny valley is a hypothesis in the field of human aesthetics which holds that when human features look and move almost, but not exactly, like natural human beings, it causes a response of revulsion among human observers.
