Mary-Kate and Ashley Olsen may have a sister named Elizabeth and a brother named James (who goes by Trent), but that doesn’t mean their Elizabeth and James brand is in homage to their siblings.

“We wanted it to be based on a relationship between a young girl and a boy and tell the story through clothing,” Mary-Kate told WWD when they launched the contemporary collection in 2007. “It’s a clash between masculinity and femininity,” added Ashley.

Brand reps also confirm to PEOPLE that the line is not named after anyone in specific.

But try telling that to little sister Elizabeth. “In my mind, that was, ‘Oh cool, that means I get free clothes,’” she tells ASOS magazine of her presumed influence on the line’s moniker. “For two years, I didn’t [have to] buy anything.” The Martha Marcy May Marlene star also wears her sister’s collection throughout a spread in the mag and was recently spotted sporting the line’s $155 sunnies.

All is fair in love and fashion?

FIND OUT WHERE TO BUY STAR-LOVED LOOKS IN: ‘YOU ASKED, WE FOUND’

Her reign as an indie darling continues, but Elizabeth Olsen is a reluctant fashion plate.

“I’m actually not very good with all this designer stuff,” the 22-year-old tells Refinery29. “I just know basic ones.”

For a newcomer, however, her learning curve is rather impressive. Along with Marni and Céline, she swears by edgier labels including Isabel Marant and Carven. “I wore an orange floral Proenza Schouler dress that I was like obsessed with to the W magazine pre-Golden Globes party,” she gushes of a recent standout look (left).

And though she’s Mary-Kate and Ashley’s little sister, don’t credit The Row designers with Elizabeth’s ingénue style. ”I don’t live with them, and they don’t dress me,” she says. “Like, I’m an adult, ha!”

But that doesn’t mean she hasn’t shopped her sisters’ closets before. “I used to do it a lot more, but I’ve overgrown them by a lot,” she admits. “I overgrew them in high school, and then all of my friends started getting their hand-me-downs.”

WANT MORE FROM SUNDANCE? CHECK OUT THE FESTIVAL’S STYLE STARS!

As the straight man in the Hangover movies, Justin Bartha is too good looking to be called attainable, but a smidge more approachable than the average Hollywood hunk.

A little out of reach, and with a solid Hollywood dating history (he dated Ashley Olsen for two years before being linked to Scarlett Johansson), the 33-year-old makes for the ideal fashion girl crush. Only one problem: he doesn’t really ‘get’ style.

“I don’t really think about it actually. For me, it’s just about comfort,” he says in a profile on Mr. Porter. “That’s the most important thing. I’m all about fit and fabrication as well.” OK, so maybe he’s not completely clueless.

And though the actor wears an Alexander McQueen jacket, Lanvin sneakers and a $265 Maison Martin Margiela T-shirt in the spread, Bartha values sentiment over designer duds. “I have a golfing shirt that my late grandfather wore,” he reveals. “I absolutely idolized him. He gave it to me and I bring it wherever I go. I wore it on the audition for the first movie I landed.”

We hope he’s not referencing 2003′s Gigli …

What do Mena Suvari, Ashley Olsen and Vanessa Hudgens have in common? Their appreciation for some seriously ravaged denim!

On Saturday, American Horror Story star Suvari covered up in a fur-lined parka, leopard scarf and combat booties. Her only ventilation? Seriously slashed denim.

That same day, Olsen stepped out in N.Y.C. sporting a menswear-inspired overcoat, a doctor’s bag by The Row and black skinnies — with conspicuously cut-out knees.

Two days later, Hudgens, whose penchant for throwback looks has not gone unnoticed this year, rounded out the trifecta. Wearing a cropped shearling and vintage-style accessories, the star completed her look with (what else?) distressed denim.

We’re always open to Hollywood-inspired trends, but want to know what you think. Tell us: Are ripped jeans a trend or simply a dead end?

WEIGH IN ON MORE STAR STYLE IN ‘LAST NIGHT’S LOOK: HIT OR MISS?’

It’s not just another celebrity sale: the ‘Goddess Adorned’ auction features fancy vases decorated with love by stars like Mary-Kate and Ashley Olsen, Bethenny Frankel, Melissa Joan Hart and more. But just like your typical celebrity auction, funds raised benefit a very worthy cause: Housing Works, a charity working hard to eradicate homelessness.

The stars involved each received a limited-edition Gaia vase by Harry Allen, then used sparkling Swarovski Elements to personalize the vessels. Frankel used black and red crystals to give a “chic” representation of her Skinnygirl brand (left); the Olsens put their design skills to use by making a miniature blazer from Italian-sourced fabrics and pairing it with a feminine skirt to “dress” their vase; and Hart made a play on her last name, covering hers in deep red breaking hearts.

Check out all 15 vases — and place some bids! — on shop.housingworks.com through Tuesday, Dec. 20 at 10 p.m. ET.

SHOP THE BEST GIFTS FROM CELEBRITY DESIGNERS

Hold on, ladies! Designers Mary-Kate and Ashley Olsen take a speedy, silly ride down a sled hill in the latest installment of their StyleMint “T Moment” series. The sisters snuggle into their winter T-shirts — and hold tight to each other — as they pass snowmen and holiday stockings on their ride.

Think your holiday plans top a seasonal sled ride? Tell the girls about your favorite winter activity, and you could win a year of tees from StyleMint. Visit facebook.com/stylemint for more information.

YOU ASKED, WE FOUND: STAR LOOKS

Covering this year’s Vogue‘s Best Dressed issue, Mary-Kate and Ashley Olsen join other stylish celebrity sibs to prove that in fashion, it’s so much friendlier with two.

But what delineates The Row designers from pairings including Kate and Pippa Middleton, Dakota and Elle Fanning, Beyoncé and Solange Knowles and Rooney and Kate Mara to handily win Vogue readers’ stamp of approval? Perhaps it’s the sisters’ keen understanding of not only the business of fashion, but also what makes the other tick.

“I feel like Mary-Kate’s constantly evolving,” Ashley recently told Net-a-Porter of her sister’s style. “What she does is when she finds a proportion or a silhouette or a specific outfit, she’ll wear it until she’s over it — which could be a week or it could be a year.”

And while Mary-Kate dubs her sister “very classic and modern,” she contends that Ashley is not without her idiosyncrasies. “There’s always sort of a sense of a bohemian vibe,” she continues, “[She's] quirky, modern, bohemian.”

WEIGH IN ON MORE STAR STYLE IN ‘LAST NIGHT’S LOOK: HIT OR MISS?’

As temperatures drop, the usually stoic Mary-Kate and Ashley Olsen warm up for yet another “T Moment” video for StyleMint.

Their latest, an adorable homage to memes and photo bombing, mixes classic holiday flicks with Internet sensations. Watch as the sisters plank, stork and owl in $29.99 trademark tees and wickedly cool accessories.

Their final gesture, however, is the one you’ll dwell on: during the month of November, 10 percent of sales will benefit Women In Need, a charity that supports homeless women and children.

CHECK OUT MORE AFFORDABLE CELEB STYLE IN ‘STAR LOOKS FOR LESS’

Blake Lively was swept off her feet by another man on Tuesday night: designer Christian Louboutin. Lively, along with stars like Mary-Kate and Ashley Olsen, Calvin Klein and Tyrese, came out to Barneys New York to fête the legendary shoe designer on the 20th anniversary of his collection.

“They are the most beautiful shoes out there,” Lively told PEOPLE of Louboutin’s scarlet-soled creations. “And incredibly innovative.” Wearing her own pair of splatter-paint snakeskin stilettos, the Gossip Girl star said “it’s embarrassing” how many pairs of the heels she owns. But she’s not alone: more than 200 fashion lovers toasted the designer Tuesday and waited patiently as he autographed copies of his new self-titled book. When he signed Klein’s tome, he wrote, “For my dear, Calvin.”

After the Barneys bash, VIP guests headed to a private celebration at Le Caprice in the Pierre Hotel — and Lively was lucky enough to get a lift, courtesy of Louboutin. There, Alicia Keys — another fan of the designer — joined the intimate group for dinner.

SEE HOW CELEBS RECYCLE IN ‘REMIX YOUR WARDROBE’

What do you get when you mix Mary-Kate and Ashley Olsen, Charlotte Ronson, Nicole Miller and PEOPLE StyleWatch? A glamorous Fashion’s Night Out party at JCPenney! The brand’s biggest collaborators were on hand Thursday to celebrate FNO in New York and all of the offerings the store has this fall.

Design director Geoffrey Henning told PEOPLE that when looking for designers to add to JCPenney’s roster, he goes for those with a “contemporary edge. We look at brands that have maybe a bit of a younger feel,” he said. “So if you look at a Bisou Bisou, I Heart Ronson, Olsenboye, you sort of get that more urban, west coast feeling. It’s a different energy, and it fits for us.”

For the fall, Henning is rolling out items inspired by the 1970s. “It’s a really polished look, so a cape is important,” he said. “And fur. If you don’t have something fur then you’ve got a real problem.” Flared pants are back, too, he said, plus lace. “Whether it’s a T-shirt with lace on it or a lace dress or skirt, it’s important,” he shared. “I call it Black Swan — it’s a little romantic in that way.”

Someone who knows all about the trends is Charlotte Ronson, who stopped by to promote her I Heart Ronson line in the midst of preparing for her Charlotte Ronson runway show. But because her two lines appeal to different shoppers, she keeps the looks quite distinctive. “You want to have them different enough because the price point is so different,” she explained. “I might use some details of the contemporary collection [in I Heart Ronson], but with JCPenney it’s a broader customer base.”

For fall, Ronson is offering “knits and sweaters, some dresses, blouses,” she shared. “But knits are always what we sell the best.”

And as if she didn’t have enough on her plate, the designer is unveiling her Charlotte Ronson Beauty line at Sephora on Sept. 15. “There are Sephora stores in around 300 JCPenneys,” Ronson explained. “Sephora came to my big I Heart Ronson launch event in L.A., we started talking … they ended up doing beauty for my runway shows, so it’s kind of a natural progression. They’ve always done an amazing job translating the look we’re going for, and they’re just a really great partner.”

While Ronson and JCPenney designers Michele Bohbot and Allen B. Schwartz mingled, guests had the chance to talk style with PEOPLE StyleWatch fashion director Kate Dimmock, and enter for a chance to swap a fashion “miss” from their closet for a “must.” Didn’t make it to the event?

SEE PARTIES FROM N.Y.C. TO L.A. IN ‘STARS HIT THE TOWN FOR FNO’

On the road to becoming a cinema darling, Elizabeth Olsen is coming into her own — and about to make a splash at the Toronto International Film Festival. But when we caught up with her Wednesday at the Missoni for Target pop-up shop event in New York City, the talk was all about style — she is Mary-Kate and Ashley Olsen‘s little sis, after all! Here’s what she had to say about shopping, her siblings and more:

Do you enjoy shopping? “I like shopping, but I have to be in a mood,” she told reporters. “I’m very lazy, I never return anything. I usually try to find someone else who’s going to want it.”

Do you have any design aspirations? “No, not at all.”

Have your sisters been role models for your own career? “It’s always just like, kind of focus on your work and not let anything else come between you and what you want to do and who you are,” Olsen said. “We don’t actually talk about work much, but they’re just great people and supportive and inspiring and creative.”

Do they give you guidance on dressing? They tell her “to always feel comfortable,” she shared.

Who are your style icons? “I always love Diane Keaton and Katharine Hepburn.”

The photos were already moving, but the video really says it all. Mary-Kate and Ashley Olsen visited children outside of Tegucigalpa, Honduras, earlier this summer, delivering TOMS walking shoes to those in need.

“We’re very aware of [TOMS founder Blake Mycoskie's] work and what he was doing and trying to accomplish, and it’s something obviously we wanted to be a part of,” Ashley shares in the clip above.

The sisters partnered with TOMS to create limited-edition shoes through their label, The Row; for every pair of TOMS + The Row shoes sold, a child in need will receive a new pair of shoes.

“It has been so much fun to collaborate with The Row and to see the girls and their friends down here on their hands and knees putting shoes on kids’ feet,” Mycoskie adds.

In fact, the experience proved quite humbling for the stars. “I think it’s really taught me a little bit more about myself and how I can be more affectionate and loving,” Mary-Kate says. “And how putting a smile on a kid’s face is … well, there’s nothing like it.”

Adds Ashley, “The children are so special, kind, they’re loving, welcoming and they’re just incredible.”

CAN YOU GUESS THE STAR BARGAIN?

Splish splash, Mary-Kate and Ashley Olsen are taking a bath … kind of. The sisters are diving into August in the latest installment of their monthly video series, “T Moment,” cooling off in a traveling baby pool.

Ever the fashionistas, the Olsens are wearing T-shirts from their new site, StyleMint.com, a members-only shopping site offering customers a personalized way to shop new, exclusive collections of eight T-shirts a month for only $29.99 each.

And just like last month, the designers want to see you in a tee, too. Through Aug. 31, upload a photo or video of yourself keeping cool in a T-shirt at StyleMint’s Facebook page. The sisters will choose the most creative entrant on Sept. 6, and the lucky winner will score a year-long subscription to StyleMint and 12 specially designed tees.

GET STAR LOOKS FOR LESS!

From frugal finds to investment pieces, there is a surprising method to Mary-Kate Olsen‘s styling madness: restraint! Revealing to WhoWhatWear.com that she prefers refined basics to offset bolder choices, the more eclectic Olsen calls a $29.99 tee from her StyleMint collection “an essential wardrobe staple.” And while she praises the “intricate, metallic detail” of a Chanel pre-fall look, it’s a streamlined carryall from The Row that she dubs “Chic. Period.”

Equally restrained are her beauty picks, which include Tom Ford’s Black Orchid perfume for “hints of sandalwood and patchouli” and By Terry Rose Balm for that perfect pout. And when a look demands that hint of edge, Olsen reaches for Elizabeth & James’s $155 “Lafayette” frames. As she insists, “The shape flatters the face.”
