I have seen the future and it is a dirty brown sweater

Having recently seen the latest (final?) installment of the Terminator series, I am once again struck by Hollywood's notion of post apocalyptic humanity. Regardless of the precise form of Armageddon that befalls humanity, there are a few things we can count on:

• The survivors will have a disproportionate representation of folks that were likely models or professional athletes before the advent of zombies / nuclear holocaust / robot uprising / plague.
  
• Hygiene will be largely unaffected. White teeth, smooth skin, and shaving tools are going to be common. (Of course, only if you are a hero. The unnamed riff-raff will still be filthy.)
• No clothing will have bright colors. Browns, grays will dominate. Snug leather garments with many belts, straps, and clasps will dominate daily wear; worn woolen sweaters dominate indoor / evening wear.
• Despite the shortages of water / ammo / fuel / food/ medicine / etc, mascara and eyeliner will still be freely available. In fact, cosmetics in general seem to have survived.

So despite the inherent horror we might associate with the end of life as we know it, it sounds like a fairly sexy period of future history. (But I suspect that the film version of Cormac Macarthy's The Road will provide a stark contrast.)

As an aside - the recent (and excellent) Star Trek is an interesting case. This series has a significant difference in tone compared to most sci-fi, because it is essentially taking place in a utopian society. Or more specifically, the Federation represents a utopian society. They wear brightly colored jumpsuits and enjoy constructive racial tensions. Meanwhile, the races outside of the Federation... those who reject the utopian ideals and antagonize the cosmos... look like post-apocalyptic humanity. Monochromatic palettes and tight-fitting garments with complex fasteners. Hmmm.
