If you were a girl that grew up in the '90s, you're bound to have a soft spot for Mary-Kate and Ashley Olsen. Growing up with them, they won over our hearts before they were even one-year-olds, both playing Michelle Tanner on Full House. Right after Full House ended, the duo jumped into creating their "Olsen Twins" brand, and their pearly whites were seen everywhere from books, movies, video games, and even cosmetics. As they grew, we grew with them, and their brand cleverly evolved from branding for children to branding for tweens. As per Nicki Swift, by the time they were 18, they were worth $150 million dollars each.

Unfortunately, as the twins grew up on camera, they never had much privacy or a normal upbringing either. As they evolved into teenagers, they became tabloid fixations, enough to wear on any young adult. After their final joint film as the Olsen twins, the girls decided they had enough of acting, and retreated from the spotlight. Instead of focusing on film, they launched two very successful clothing brands, and thus started a new empire - this time in fashion. Since becoming heavyweights in the fashion industry, the girls have come to the realization that clothes are truly their calling, even giving up re-joining their Full Life cast for a reboot of the show that happened back in 2016.

We've rounded up 25 photos of the Olsen twins, taking a trip down memory lane from the time they were children to the women they are today.

25 They Both Played The Same Character On 'Full House' When They Were Just Nine Months Old

With adorable little faces like this, it's no wonder Mary-Kate and Ashley were cast as Michelle Tanner in Full House back in 1987. According to Cosmopolitan, the two were chosen when they were just six months old and started filming just a few short months later. The girls definitely had star-appeal, and stole the show from the rest of the cast before they were even able to start speaking!

Wonder why they both got cast to play one character? It turns out, child-labor laws were pretty intense, and the series got around that by hiring the twins instead.

24 The Duo Had To Both Wear Dentures In The Initial 'Full House' Years

When someone mentions dentures, you immediately think of pensioners, but never kids or young adults. While on the set of Full House, the producers ran into a bizarre predicament that really required them to improvise for the sake of continuity. It turns out, twins don't lose their baby teeth at the same time. According to Nicki Swift, both Mary-Kate and Ashley had to wear dentures so their teeth matched when they took turns filming. This definitely may have taken a toll on the twins mentally at a young age, since it forced them to maintain looking exactly the same pretty much all the time.

23 They Jumped Into Their First Feature Film Together Just Months After 'Full House' Ended

Right after Full House ended in May of 1995, the Olsen twins jumped headfirst into their first feature-length film together, It Takes Two, in November just a few months after. From then on, thanks to their fans, their tween careers took off, with most of us fondly remembering their direct-to-video series along with later on their two starring shows, So Little Time and the animated series Mary-Kate and Ashley in Action!. If you take a look at their IMDb pages, you'll notice that the duo were little machines, and before Full House was officially over, they had already starred in 4 films, along with launching The Adventures of Mary-Kate and Ashley in 1994, as well.

22 They Were Into The Boho Chic Look Even When They Were Kids

As the Olsen twins grew up, most of us have seen them looking like boho queens in recent years. The above photo, however, shows their bohemian-chic fashion taste goes back to being 8-year-olds. Sporting sunkissed skin, and layers upon layers of flowy frills and ruffles, the girls still rocked the look quite well.

Since then, the girls have mastered the art of the boho look, going for wearing oversized-anything and realizing that more is more, quite literally even in terms of their long, beachy locks and accessories galore. They love clashing with prints, tones, and silhouettes, always managing to look effortlessly stunning.

21 As They Got Older They Still Matched, But This Time Had Their Own Color Schemes For Their Outfits

As they grew slightly older they still matched their outfits, but not all the way as they did as tots. Still the queens of Y2K fashion, the twins are seen above sporting styles that girls have been flocking to in recent years again! From the jelly sandals to the very small sunglasses, the girls are simply fashion inspos, time and time again.

Not matching entirely means the girls started growing into their own, and shortly thereafter their films even started giving them stereotypes so both sisters had a very distinct personality, very different to the other.

20 By The Time They Were 12, The Girls Were Already Millionaires

Unlike most tweens their age, the girls were already millionaires by the time they turned 12, later turning it into a billion dollar empire. As per AOL, in 1993, the Olsen twins created and began co-owning Dualstar Entertainment Group, which was set up by their manager. This was the company that later went on to produce all of their well-known films and television series along with a collection of children's books and games. At only 10 years old, the girls became the youngest self-made millionaires in American history and once they were given the reigns on Dualstar on their 18th birthday, they became the richest teenagers in the world.

19 By The Time Their Popular Sitcom Ended, They Made It To The Top Of The A-List

Because they were so popular when their fans were children, when their following grew, they grew with them, becoming "It" girls well into their teens. As per Cosmopolitan, the above photo shows they were constantly invited to cool things, such as the release party for the *NSYNC album, Celebrity.

As the girls turned into teenagers, Dualstar made sure that the themes in their films were right on track with what would happen to girls their age, cleverly adding romantic subplots to keep their fans hooked. When in Rome and Passport to Paris, for example, both had teenage girls screaming with delight.

18 Skipping Prom To Host 'Saturday Night Live', The Twins Finally Graduated High School And Began Classes At University Just Months Later

Not many teens can say they skipped their prom to host Saturday Night Live, but that's exactly what happened to Mary-Kate and Ashley. According to Screen Rant, during the show's opening monologue, Ashley poked fun at their lives and prom, saying she was sad to miss out on prom because, "we'll never know what it's like to ride in a limo, and wear fancy dresses, and have someone do our hair."

Shortly after hosting SNL the girls graduated from high school and only months later began classes at New York University proving they weren't just hard workers at their jobs, but focused on their education, too.

17 The Girls Finally Grew Up In 2004 And Stopped Matching On Red Carpets, Along With Starring In Their Final Movie Together

2004 marked the year that the Olsen twins made their final movie together and with that, stopped coordinating their outfits. New York Minute showed the girls as two completely opposite characters, pushing their individuality to their fans quite clearly. Mary-Kate was seen as the free-spirit, while Ashley had more of a put together, prim and proper look.

As per Nicki Swift, the movie, unfortunately, tanked, showing that their transition into more mature roles wasn't something their fans or critics were necessarily looking for. The girls then decided to retreat from the spotlight, and put their time and focus on other projects, such as fashion.

16 The Time They Were The First Ever Twins To Be Placed On The Hollywood Walk Of Fame

The Hollywood Walk of Fame is essentially an entertainment museum, hosting the names of famous celebrities and fictional characters that are written on the stars. According to China Daily, the twins were honored at the same time they promoted New York Minute, cleverly tying the press together. In unison, they told the crowd that it was "a great honor", with Ashley making sure to thank all their family and friends, cast members, Dualstar, and of course, their fans.

The girls posed with their mom and siblings, with Mary-Kate wearing a gorgeously slinky purple dress and sporting darker hair, while Ashley went more formal in her glittery white dress, channeling old Hollywood glam with her platinum blonde locks.

15 The Time They Infamously Got Slimed At The Nickelodeon Kids' Choice Awards

Having stars "slimed" was something Nickelodeon was known for, especially at the Kids' Choice Awards. Back in 2004, while promoting New York Minute, the Olsen twins got notoriously slimed, clutching each other in fear on stage as they got dosed in the sticky green goo. As per Daily Mail, the history of getting celebs slimed goes back to the late '80s and '90s, with the ingredients making it surprisingly edible, as they were mostly food coloring and various foods. Some ingredients in different versions included vanilla pudding, applesauce, and even oatmeal. It turns out, the Olsens didn't have much to be afraid of after all!

14 Moving Away From Film And Steering Into Fashion, The Duo Launched Their Own Line, The Row In 2006

In 2006 the twins were almost 20 and slowly began building their fashion empire. Only two short years after releasing New York Minute, Mary-Kate and Ashley launched their first collection for The Row, consisting only of seven garments. It originally started as a personal project with the challenge of creating the perfect t-shirt. According to AOL, it was a hit, and Barneys New York bought it all.

The very premium, high-end label has led them to win a total of four CFDA awards at the highest honor a fashion designer can receive. This proved that the girls really do have a knack for fashion, and their foray into clothes wasn't just another celebrity clothing line.

13 Becoming Millennial Fashion Icons, The Girls Brought Chic Oversized Sunglasses Into The Limelight As Their Trademark Look

Big sunglasses have had their time in the spotlight before, thanks to the likes of Jackie Kennedy, and hippie queens of the 1970s. Mary-Kate and Ashley gave this trend another whirl, making it their trademark look that caught on in the world of fashion.

The girls have popularized other trends as well, oversizing practically everything in their closets - not just their sunglasses. Wonder where the twins find inspiration themselves? Pick up a copy of their book that they co-authored called Influence, which was published back in 2008 and featured interviews with designers like Diane von Furstenberg and Karl Lagerfeld, as well as other high-profile photographers and celebrities.

12 After Ditching Acting, The Girls Still Supported Their Younger Sister Elizabeth As She Started Gaining Traction In Her Acting Career

As the twins left the acting spotlight of Hollywood after New York Minute, their younger sister Elizabeth gained traction, especially after starring in The Avengers. Despite all her success on camera, it turns out Elizabeth almost quit acting due to watching how it affected her sisters, according to E Online. When Mary-Kate had a health scare back in 2004, the media frenzy that surrounded it was ruthless, showing Elizabeth the harsh realities of the business. She's been quoted as saying, "that was when the media was what I found to be abusive to my sisters, and I thought I really didn't want to be in the industry. They would follow us shopping and [Mary-Kate and Ashley] would almost get into car accidents because of the paparazzi, and I didn't want to be a part of it."

Ashley has raved about Superga in past saying, "I really don't think there's anything like this brand. It's a tennis-shoe brand with 100 years under its belt." With its minimal design, it's no wonder the Olsen Twins have taken over.

Growing up in the spotlight when they were both under a year old, the Olsen twins have always had a special bond that they could not share with anyone else. With all their joint TV shows and movies, interviews, and countless paparazzi moments together, it's no surprise that the girls had to form a special handshake and code that they use with one another in public. According to Vanity Fair, videos have been uploaded in recent years of the Olsen twins hugging and squeezing each other's hands in quick succession. When asked about it, Mary-Kate has said, “We have this little thing when we love each other where we’ll squeeze each other like three times,” she said. “Then I’ll squeeze her hand back four times. Like, ‘I love you, too.’”

When they do have their photos taken, they usually look quite refined and reserved, rarely showing too much expression as opposed to their wide smiles as children.

This is why it was so nice to see the girls laughing and dancing in an intimate shot at their friend's wedding last year as bridesmaids, according to Marie Claire.
