They don't mean that people look like they are from an older time. They're talking about the age people look (as in this person looks like they're 30 or this other person looks like they're 70).

Is this really just a case of hair and clothes? To me this looks like a movie filmed in a high school where all the actors are nearing 30 but they try to pull it off anyway.
I’m open to the idea that it’s as simple as sun damage. Kids especially are spending so much more time indoors where their skin isn’t being ravaged by the sun.
