I'm over 30. Where's the fashion for me?

Be forewarned, this is a bit of a rant. I discovered a major point of irritation to me personally this morning and I am really wondering if anyone else has noticed.
I am a woman over 30. I have a dressy, all adult holiday party to attend in the near future. I have a dress picked out, Liz Claiborne wine and black floor length velvet. I am a bit nervous as I have been out of the social arena for quite some time, so I start looking up current styles. This is where the problems start. I start noticing almost everything targets females under 30, and while I could still wear much of what is offered, all too often the looks were inappropriate for meeting your husband's boss for the first time.
I found a page with a list of what I shouldn't wear, which was decidedly unhelpful. I did not need to be told a micro mini or regular mini skirt would be inappropriate for my age or that I should avoid glitter because it accentuates wrinkles.
Where is the style? Where is the elegance? Am I forsaken by the fashion industry courtesy of my over 25 status? I don't want a matronly version of some twenty-something's club wear or even a slightly less sparkly version of her showy holiday dress, vintage inspired or not.
I want glamour that isn't the neon and flash kind. I want clothes that are tailored, feminine, and have a bit of slink to them even if you are wearing a three piece suit.
I have no desire to look like some plastic fashion doll. I have wrinkles and I earned them. I would like clothes that respect that and the fact that women over 30 are sexy, without having to dress like they are barely twenty.
