“Is Uncle Frankie Aunt Tilly’s brother?” I asked mum. I was 11 years old and visiting an old aunt and uncle in Singapore when I innocently addressed this question to my mum. She laughed and replied, “Hello…? He’s her husband!” But it was very unsettling to me and I kept wondering why do some couples look alike.

I remember being puzzled, “Then why do they look alike?”

Mum’s smile changed to a pensive look. “I never really saw a resemblance before. But now that you mention it, they indeed look alike.” Was it just our mind playing tricks on us?

When we got home, we rummaged through our collection of old photos and found a wedding photo of Aunt Tilly and Uncle Frankie taken years ago. They definitely didn’t look alike then. So how did they grow to look alike?

Why Do Couples Look Alike?

This question pops up in my head every time I meet a couple who seem to resemble each other, particularly older couples.

I decided to throw the question to a knowledgeable group of friends and got some rather interesting answers. None of them are subject experts, but ordinary people just like you and me, mulling over this strange magical thing called relationship.

According to them, couples that look alike are soulmates. We don’t know if this is really true, but there are some points that definitely indicate this.

Couples Resemble Each Other In A Happy Marriage

Is it love, is it familiarity or is it the habit of staying together? Looking alike could be a sign of healthy and happy marriage too. We try to figure out this phenomenon of convergence of appearance.

1. Familiarity breeds similarity

It’s funny but when you live with someone for a long time, you actually start mimicking their expressions and mannerisms. You may imitate the way they smile or grimace or simply raise an eyebrow.

Spending too much time with one person actually does make you a little like them. So sometimes when we feel like couples look alike, it may just be them acting and behaving in a similar way.

You unconsciously adopt their expressions and gestures because you see them every day. That’s what most people mean when they say, ‘You’re so alike (in mannerism).’

2. Sharing life experiences together

What does it mean when you and your partner start to look alike? It could be a manifestation of your shared journey. When you share experiences together, these are etched on your face. So if you are laughing a lot together, you could develop similar laugh lines around your eyes and at the corners of your mouth.

Likewise, if you are stressing over situations together, you could have similar furrows on your forehead. Wrinkles on the same spots on your face could make couples look alike, you know.

3. You are what you eat, and drink

If you are eating the same kind of food, processed or cooked in the same way, chances are that, it’s going to settle on your face and body the same way. For example, if your diet has a high concentration of carrots, you may develop a similar skin tone – orangie perhaps!

Or if both of you enjoy your alcoholic beverages, over time, both your faces will look puffy and bloated and you’re going to have a nice beer belly. So much for similarity!

4. Having the same hobbies

If you and your partner love the outdoors and are perhaps biking together, you may both get a nice tan. Your features still look different but if you are both spotting freckles and pigmentation, you now have something in common to make you look alike. And that explains the convergence of physical appearances.

Similarly, if you like the same type of music, chances are your sense of fashion too is influenced by your taste in music. So both of you could end up wearing the same kind of clothes and accessories without even noticing it.

5. Matching your styles

It’s easy to get influenced by each other’s clothes and even hairstyles as you grow old together. This may sound quirky but many couples do this for convenience. They buy T-shirts of the same color and are so happy about it that they post on social media to let others know how compatible and alike they are.

Some couples look alike after visiting the same hair salon. They point to their spouse and say, “Just cut mine the same way.” Frankly, as you age, you just want any style that’s comfortable. How can you not look similar if you both have the same hair crop?

6. Likes actually attract

People tend to choose a partner who has physical characteristics similar to their or a parent’s. If you have blunt features, you feel comfortable if your partner has blunt features too. This is a key factor that builds the foundation for similarity in looks as you grow older.

Some people even believe that couples who look alike stay together longer. Humans thrive on familiarity and comfort, and actually prefer being with someone long-term if they are more like their own self.

7. Blame it on aging

When you are young, your facial tissues are perky. There are clearly defined compartments holding skin and other structures in the right places. With age, your features begin to melt into each other like hot wax, and with a definite migration downwards.

This law of gravity applies to all of us but when you are a pair, the visible signs of aging make you look alike.

Does this explain why couples look alike?

Couples look alike

Well, basically, it is the perception of others. Just because you copy each other’s expressions and mannerisms, doesn’t necessarily mean you begin to look like your partner. However, when others see the two of you do so many things the same, they begin to imagine you are so alike even in looks.

It’s all the factors combined that make you feel like these couples look alike. Some say, happiness as you grow old, can make you look alike. I know many happily married couples who don’t look alike at all. So this theory works for some people but not for everyone. And thank God for that or I’ll be sporting a walrus mustache by now!


1. Do soulmates look alike?

Some people do believe that couples who are soulmates are together longer. The pair pick up each other’s behavior and mannerisms that make them seem more alike.

2. Do couples resemble each other?

Yes. After spending so much time together two people naturally adopt similar characteristics, preferences, and dislikes.

3. What does it mean when you and your partner start to look alike?

It shows that you two are getting along well. Clearly you’re attracted to them and their way of thinking, style, and mannerisms.
