Kiernan Shipka, 14
Perhaps one of the more conventionally stylish ladies in our roundup, teen queen Shipka knows her way around a good outfit. She's not afraid to be adventurous, but she never, ever looks messy.

Elle Fanning, 16
So much of the younger Fanning's appeal is her prim-and-proper princess aesthetic. When she's not wearing a tiara, you can often spot her in a myriad of pastels with ultra-femme accents.

Chloë Grace Moretz, 17
Moretz is on the fast track to perpetual best-dressed status. She perpetually kills it with risks and out-of-the-box combinations, including a good jumpsuit; the girl loves a good jumpsuit.

Emma Watson, 24
How much do we love Watson's ladylike-meets-edgy style? We've already counted the ways—multiple times—but it really never gets old.

Elizabeth Olsen, 25
Much like her hippie character in her forthcoming summer flick Very Good Girls, the eldest Olsen sis maintains a fun bohemian vibe; her personal style stamp is on essentially every outfit in which she steps out.

Emilia Clarke, 27
My sun and stars! Clarke is a little bit of a sex kitten, right? And she knows how to embrace that without looking like a pin-up.

Olivia Wilde, 30
As 2014's awards season circuit proved, snarky new mom Wilde mastered styling her pregnancy bump in a truly impressive way. Plus, her off-duty style is as hip and relaxed as is her fun-loving personality.

Lupita Nyong’o, 31
Lupita. Nyong'o. Need we say more?!

Jessica Alba, 33
You can't deny the simple truth: this street style stunner knows how to balance feminity and simplicity in an expert way.

Gwyneth Paltrow, 41
We'd be remiss if we didn't include the industry's chief Goopette, GP. She may be 41, but she has the bod of a crazy-fit 25-year-old—which, you bet, she flaunts in every sense.

Cate Blanchett, 45
Blanchett exudes a regal quality amongst her movie star colleagues, which she uses to her advantage when she hits the red carpet.

Sandra Bullock, 49
Next month, Bullock turns 50—and she looks better than most of my 20-something colleagues. So, what's her magic, exactly?

Vanessa Williams, 51
I realize this may sound odd, but Vanessa has two of the best legs in the entertainment biz. And to wit, she knows how to showcase them without looking at all like a floozy.

Julianne Moore, 53
A total siren, Moore often dresses in slightly younger styles that have been more tailored to suit her 50-something age. Take her blue Cannes dress at left: Kiernan Shipka could totally pull off the color and style, but it's a breezier fit that really does work for her.
How many 56-year-olds can rock a studded, slim-fitting tuxedo on the red carpet? Not many.

Meryl Streep, 64
The one, the only, the Meryl Streep. Not much else needs to be said in regards to this enlightened deity of a human.

Diane von Furstenberg, 67
DVF's designs are oh so youthful, and yet so many of her patterns work so well for a woman of her age. She's a real beauty, inside and out.

Helen Mirren, 68
This dame is a total babe who knows better than anyone that it's important to dress fittingly for your age, even if you are a solid 56 years older than one Elle Fanning.

Catherine Deneuve, 70
If you're able to land a Louis Vuitton modeling gig at age 70, you're doing just fine. (I'm talking to you, Deneuve.)

Blythe Danner, 71
As half of the only mother-daughter coupling on our list, Blythe isn't afraid to showcase her quirky side—so long as it's clear that her daughter-slash-lifestyle guru Gwyneth has whipped her into shape.

Jane Fonda, 76
Years as a fitness guru and feminist icon have made Fonda entirely at one with her slammin' body, as well as her age.

Carmen Dell’Orefice, 83
There's a little bit of a Cruella de Vil vibe happening here—but hey, Cruella was one chic lady.

Barbara Walters, 84
Now that Barbara has officially retired from being on camera, what is she going to do with all those terrific monochromatic pantsuits?

Elaine Stritch, 89
We'll just leave you with this 30 Rock snippet (Stritch played Alec Baldwin's character's persnickety mother, Colleen Donaghy, on the series): "Oh, for crying out loud, Liz. You see, that's what feminism does. It makes smart girls with nice birthing shapes believe in fairy tales. Stop waiting for your prince, Liz."
What a doll. In the words of Miranda Priestly, that's all.

Iris Apfel, 92
Undeniably marching to the beat of her own sartorial drum, we're so pleased with Iris' innate knack for color, pizzazz and individualism. She proves every single day that being 92 can—and should—be a great time.
