Looking at Moore's own fashion history, she's changed a lot, too. She has done the menswear thing, the retro siren and many plunging necklines. She's been bald and buff - and totally bare. (Remember the Vanity Fair cover when she was pregnant in 1991?)
In recent years, she has developed more of a signature look - one that's both sophisticated and sultry - which has won her praise from fashion insiders.
"We have to remember it's OK to take risks. Sometimes it will work and sometimes it won't. For me, I know there's a certain kind of balance of criteria. I like things that are classic. I want to know that I'll look in my closet five years from now and that piece still has a place. I don't have room or time for something's that just absolutely of the moment."
She has no problem taking some cues from the past, though.
"I look at Katharine Hepburn, from the 30s and 40s, and the women of the 70s, Bianca Jagger," said Moore.
"When we're young, we're finding ourselves, what we like. I can say there are certain things that remain a constant. I've always loved vintage. I've rested in a place that's classic, with a twist."
That's the look you see in the Ann Taylor ads, shot by top photographer Patrick Demarchelier at one of Rockefeller Centre's rooftop gardens in New York City against a backdrop of towering buildings.
In one ad, the star of Ghost and A Few Good Men stands confidently, hands on her hips, wearing a 60s-esque beige wool cape and a black blouse edged in lace.
In another shot, she sports a sexy-chic long V-necked grey sweater accented by faux fur. Moore hadn't worked with Demarchelier since he photographed her as the cover of an issue of Harper's Bazaar in the 90s, one of her favourite shoots, she said.
The collection also includes animal-print jackets, tailored tweed, wide-legged pants and blingy statement jewellery. Moore added her own creative slant to the ads, suggesting the pairing of a leopard-print shirt with khaki pants, and the faux fur-trimmed sweater.
"That was actually one of my favourite pieces, when I first looked through the collection," said Moore.
Married to actor Ashton Kutcher and mother to three daughters with her ex-husband Bruce Willis, Moore said she definitely identified with Ann Taylor's working-mum demographic.
Looking like a casual mum herself during her break on the LA photo shoot, she charmingly wore Harry Potter-ish designer black round glasses and loose-fitting jeans. On set, she transformed, moving fluidly into poses, doing yoga stretches between takes.
There's back-and-forth style advice between her and her daughters, including oldest Rumer Willis, a budding actress featured in ads for Badgley Mischka's spring 2011 collection.
"There are things that I might wear with flats that they would put with heels," said Moore.
"They definitely stay at a kind of cutting edge because they're still in that experimental stage, which is important to remember. You keep going outside your comfort zone. When you get too confined to 'This is what I know works and looks good,' I think you also don't stay fresh and current."
Moore still can push the envelope. For example, to this spring's Costume Institute Gala at the Metropolitan Museum of Art, she wore a strapless Prabal Gurung gown dripping in black feathers topped by a Philip Treacy head piece.
"Some of the kind of unspoken rules of what we're allowed to do at this age, and what you can get away with, really comes down to what's in your comfort zone, what makes you feel good about you," Moore said.
"I think a part of it is on average we're living 34 years longer, so it's really changing, how we look at ourselves at different times. There might have been a time when we would say, 'Post 40, dress above the knee, I shouldn't be doing this.' But that depends on the person. Fashion style really comes from the inside out."
