Although they often looked identical as children and young teens due to the same hairstyle and hair color as well as matching outfits, Mary Kate and Ashley Olsen aren't identical twins. One easy way to spot the difference is that Mary Kate's eyes are rounder in shape.
The Olsen twins were a hit sharing the role of Michelle Tanner on the popular sit-com, Full House (1987-1995). Many viewers felt like they watched Michelle Tanner grow up on the show since her character appeared first as an infant then stayed on through the years from beginning to talk to being a toddler to going to school.
3. Even As Pre-Teens No Longer In 'Full House,' The Olsen Twins Dressed Alike
Although some kids turning 13 may dress (ahem) rather independently, we didn't see that from either Mary-Kate or Ashley Olsen. They continued wearing the same hairstyle and typically had matching outfits on, usually just in different colors.
5. In Their 20s, The Olsen Twins Made Their Last Movie Together
Looking back before the more radical changes the Olsens made in dressing as they turned 30, it seems to have started mainly with the manes. That is, it was the hair texture and hairstyles that started to change from one twin to the next.
7. The Olsen Twins Really Used Their Heads...As An Individual Style Statement
Once down that road of having different hair, Mary-Kate and Ashley never seemed to look back. The color differences and textures only became more pronounced as they got older. They still would often wear a similar color of clothing, but each twin gave it her own style.
8. At Age 30, The Olsen Twins Began To Really Look Different From One Another!
Hair styles and outfit pieces began becoming even more different when the Olsen twins turned 30 in June of 2016. They were both so gorgeous; just not looking like a matched set anymore like they did as children.
9. At Times, The 30-Year-Old Olsens Didn't Even Look Like Sisters Anymore, Never Mind Twins!
Sometimes, perhaps due to drastically different hair colors and makeup shades, even the Olsen twins' skin colors appeared very different. It also seemed that very often if one twin wore understated jewelry, the other wore a bolder piece. Did they communicate about appearing different?
Even when they're dressed similarly, it seems that the differences in how they look is getting more pronounced as they get older. They're sororal twins (the female version of fraternal), yet somehow always looked identical. It seems with age the differences between them are becoming more noticeable.
If you look at a picture of them now, it is almost impossible to believe that they were once mistaken for identical twins. Hair, clothing and make-up went a long way in helping the two look alike, but it could just be that aging is emphasizing the features that makes them look dissimilar. Time will tell.
13. Different Looks For The Grown-Up Olsen Twins, Yet Equally Beautiful
Although they do, as 30-something grown women, look very different from one another, they both dress tastefully. That stands to reason as the Olsen twins work together in their fashion design business. It seems they like to express that although they are twins and business partners, they also have two separate minds. As adult professionals, they can think for themselves, even if they are always a team.
