Angela Bassett: Her IMDB page says her birthdate is 8/16/58 (a Virgo like me), so it’s not so much that she’s aged well (48), but she’s smoking hot nonetheless. Her commercial for “Regenerist” shows way too little of just her.
My dad. He’s in his late 60’s, but looking at him you’d probably guess an age in the 50’s. He has very little gray hair, and the only damage to his hair line is a small bald spot.
God, I hope I got his hair genes. I do take after him 
Lauren Bacall, always stunning, classy,aging elegantly, and into her eighties, Here’s lookin at you, kid.
She’s my bellweather of how to do it.
Ageing elegantly? I gotta figure out how to do this. I have one clue, though, based on one of my friends: inner peace helps a lot.
Lee Radziwill at age 70 (she’s 74 now, I believe).
&
Gloria Vanderbilt at age 80 (82 or 83 now).
I’ve seen both on television lately and while I’m not usually attracted to women old enough to be my mother, I have to admit that I found both of these women to be very attractive and alluring. Money aside (cough,cough) I would happily explore a romantic relationship with either–provided that they were interested in me and not already dating one of their usual multi-billionaires, that is. 
Emmylou Harris has aged beautifully, both in her look and her voice. (She’s about to turn 60.)
Alec Baldwin - 49.
Gwen Stefani - 38. Saw her on Idol last night, she looked 21.
Jeff Goldblum - 55.
Mary Woronov is 63 and still mesmerizing.
Carly Simon has kept herself looking mighty fine:
2005 Tour
(She’s 60 years old there. Wow 
)
The actress Theresa Russell is 50 this year and still looks great. She keeps herself in great physical shape as I also believe Mary Woronov does.
Yes I second Beware of Doug’s nomination of her.
I have to disagree with you. I do think she looks beautiful with age, but her beauty doesn’t belie her age. If anything, I thought was she older, well into her 60s.
I’d have to say, Diane Lane:
In 1979 (as a 14 year old)
In 1989 (so says the Wikipedia cite, age 24)
Now (age 42).

Michelle Phillips. She is in her 60’s, the only surviving member of the Mamas & the Papas and looks marvelous
No mention of Michelle Pfeiffer? She’s almost 50.
Patti Labelle is 62. I think she looks terrific.
I’m surprised Iman hasn’t been mentioned. If I look like her at 52, I’ll be one happy woman.
Oprah also looks pretty damn good. She wears a ton of makeup, but she doesn’t have any wrinkles. And she wears her makeup well.
Pam Grier is also a badass.
“Bill’s 32. He looks 32. He looked it five years ago. He’ll look it 20 years from now. I hate men.”
From All About Eve, of course…
Whoof!
I came in here to nominate Claudia Schiffer, having recently seen her on a commercial and thinking she has aged well over the past 15 years. Turns out she is only one year older than me… so not that old. But still very nice on the eyes.

Bernadette Peters. Born 1948.
Sophia Loren.

Can’t find a recent picture, but Lena Horne is 90. Around 10 years ago she still looked hot.
