One of the fashion mags Bazaar, I think has a regular feature about Looking Fabulous at Any Age, where “Any” falls somewhere between the 20s and the 60s. Of course, this is top-down stuff: you’re being given your dressing orders from on high.
“I think it would be very interesting to get guest posters from different age ranges (20s, 30s, 40s, etc.) to discuss style and style evolution, body image evolution, how they address trends, what they find work appropriate, etc. At 37, I’m not a kid anymore, but I’m infinitely more confident and have style that I never had in my 20s.”
The participants ranged from 23 (almost) to 56, and each of them had something interesting to say. For instance, Audi from Fashion for Nerds she’s 40 contributed this bit of wisdom:
I’d say that my current style reflects more facets of my personality than it ever has before; I’m no longer afraid to be stylistically schizophrenic and have embraced the fact that I have many sides, which will translate differently into my outward appearance on any given day.
I found this through Une femme d’un certain age, who is a participant in that survey.
