Apocalypse fa-shun.

Minki Cheng

I've only given this a little bit of thought.

If it is the end of the world, fashion is going to be the very LAST in what you're thinking about. Unless, its for survival techniques. Specifically, intimidation and camouflage. There are always two kinds of people in post-apocalyptic movies: foragers, and hunters. 

Personally speaking, I would be a content to forage and hide wearing simple camouflage clothing for the rest of my life. I would be content to avoid all confrontation, like a little turtle. No more high heels, make up or jewellery, just camo and the basics for me.

Then again, if you're a bad ass / cannibal / Queen, you've got to go for the intimidation route. Here's a good look to take inspiration from.

Tina Turner does good chain maille chic in Thunderdome.

Heels are out of the picture, because you have to be able to chase your prey, 

but who says you can't have a little flair?

It's funny though, because studs used to be scary, but now they're not.

 Face paint maybe? Nope. That's only scary in the sad way.

A swishy fringe jacket for intimidation. Anything that makes you seem a little bigger

 than you are, not unlike the transformer owl. 

Leather pants. Preferably.

Forager wear:

Now, is this more survival friendly or Freaks and Geeks?

Sexy camo pants. You have to encourage re-population right?

Comfortable shoes are a must, preferably something that you can run in with treads, 

for climbing big hills and running away from cannibals. 

All clothes from Nasty Gal. Because I'm too lazy for this.
