No New Fashions In The Future: Averted over the very long term; over the shorter term, though, I beg to point out that just as with Eternal English, generational turnover is slowed way the heck down in comparison to lifespan – potentially endless – which also slows the rate of fashion change.  Or, at least, the rate at which things go out of fashion (see also: Awesome Anachronistic Apparel).  Fashion innovation certainly continues – but, frankly, it’s doubtful if a lot of things will ever go out of fashion at all, so long as their partisans are still living, and they don’t plan to stop any time soon.

Also played straight for a lot of ultra-formal and – especially – ceremonial dress.
