I agree that age appropriate is necessary if we wish to be a part of society and not the "fringe" element. That being said it doesn't mean that you must dress your "Chronological" age. By that I mean that as my wife tells me, when I dress I look about 45 and not my true age. Therefore I dress for that age, not 18, not 63, not 30. If you "appear" younger than you really are (and what woman doesn't strive to do that) then you should dress for that age if you hope to be seen as a person and not as an oddity.

Yes, hemlines drop as we age, but if you still have the legs then go for it....within reason. I still like my skirts a bit shorter (1 or 2" above the knee) and I'm told I have the legs to wear skirts that short. I would not however wear one that I couldn't sit in for fear of displaying my reality...so to speak.

At home...anything goes when the shades are down and the doors are closed.
