Yeah, that's fair enough paintbox. :) (Replying to your first post there.)
I think I just get a bit annoyed sometimes at the opposite, which you also often see on these boards, a kind of militant refusal to accept that anybody might ever want to take their age into account when dressing. You know the kind of thing when a poster asks "is this too young/old for me?" and six brusque responses of the "Wear what you want! Why do you give a fuck what anybody else thinks if YOU like it?" type - which always makes me wonder what the point of S&B discussion boards is, is nobody is allowed to solicit opinions on taste.
FWIW I definitely don't think that dressing "for your age" is an inherently unstylish thing to do, rather the opposite. My mother is in her 70s, so long past middle age, and frequently wears fashionable, pretty and yes sometimes frivolous things! Frankly, these days I genuinely think she looks better than I do. But I also think that part of the reason she looks so wonderful, and is such a style inspiration to me, is that she takes her age into account rather than ignoring it. M&S Classic Collection with its droopy baggy T-shirts etc is not for her! But she does choose to cover up a lot more, pays more for expensive tailoring and fabrics (and alterations, where necessary), and takes her changing skin and hair tone into account (e.g. she now avoids black as it drains her, and goes for rich navies, browns or jewel colours instead). Dame Helen Mirren, I suspect, adopts the same approach and looks tremendously stylish and elegant.
FWIW I am a little younger than you and have been shopping at the shoe shop frequented by all the rich old ladies in my town for the last 15 years because the quality and comfort of the brands they stock is unparalleled and I couldn't possibly go back to the flimsy crap peddled by the other shoe shops after getting used to these. :D I'm usually much younger than everyone else in the shop, which is fine. I just select styles rather carefully to avoid anything where there is a really obvious clash between my age and the demographic the shoe is designed for.
