Almost no-one here is in the position to tell anyone what they should and should not wear and no-one's asking for that. Still, I do think were allowed to form opinions on other people's outfits, and other people are allowed to ignore your opinion if you happen to express it. If that's 'judgmental', so be it. I'm not really worried about the 'fashion police' as much as I'm worried about thought policing.

Dressing 'age appropriate' is no different than any other fashion rule and you may get away with breaking the rule. That however is very subjective, and in my opinion, not many can get away with miniskirts or ultra-miniskirts or whatever.
