Korean Couple Culture: Matching Outfits, Anniversaries, and More

 

Written by a Korean-born writer who spent three decades in the airline industry, sharing what growing up in Korea actually looks like.

Introduction: The Fastest Way to Spot a Korean Couple

Walking around Seoul, you might almost miss it at first. But once you notice it, you start seeing it everywhere.

Two people in matching beige jackets. A couple in identical sneakers walking side by side. A man and a woman on the subway, each carrying the same-colored tote bag.

Korean couples tend to make it fairly visible that they're together, and they do it deliberately.

In short: Korean couples often signal their relationship publicly through matching outfits and tracked anniversaries, especially the 100-day mark. It's less about performance and more about a shared, deliberate way of saying "we're together."

This article takes a closer look at two aspects of Korean couple culture briefly introduced in an earlier post on Korean dating culture: couple outfits, or couple look, and anniversary culture. This piece gets into how they actually work, why they developed, and what they look like in practice today.

Growing up in Korea, it's hard to pinpoint exactly when matching outfits became such a natural part of the landscape. At some point, it was just there.

Foreign friends, though, tend to notice immediately. "Did they plan that?" Yes, they did, and in Korea, that's not excessive. It's just one way of saying you're together.

Couple Look: Making the Relationship Visible

What Couple Look Actually Is

Couple look (커플룩) refers to couples deliberately wearing coordinated clothing or accessories. This doesn't always mean identical outfits.

More often it means the same color palette, similar styles, or matching accessories. Some couples wear exactly the same outfit, others simply wear the same color on the same day. Beyond clothing, couple look extends to matching rings, phone cases, sneakers, and bags.

Why This Feels Natural in Korea

In many Western contexts, deliberately matching outfits with a partner can feel like too much, a little theatrical or clingy. In Korea, the reaction tends to be different.

Korean culture places real weight on making relationships explicit and visible. Just as the formal gobaek (confession) marks when a couple officially becomes a couple, couple look functions as a way of announcing that relationship to the world around them.

Korean dramas and advertising from the 1990s and 2000s reinforced this by consistently portraying matching outfits as romantic rather than excessive, which likely helped normalize the practice across generations.

For many Korean couples, matching outfits aren't really about how they look to other people. They're about the process of choosing together.

"Let's get these and wear them this weekend" is a form of attention toward the other person. The act of coordinating, of thinking about what the other person would like, carries its own meaning — it's less about the outfits and more about the gesture.

Picture two people browsing a clothing rack together on a Saturday afternoon, holding up two shirts in the same shade of navy and asking each other "this one, or this one?" That small back-and-forth is the actual moment couple look is built on, long before either shirt gets worn out in public.

What Couple Look Looks Like Now

Full matching outfits, wearing exactly the same thing head to toe, are less common than they used to be. That version has quietly dialed back over the years.

What you still see regularly on Seoul streets is the softer version: the same sneakers, matching caps, similar-toned outerwear, or a shared accessory. The direction has shifted from "identical" toward "coordinated," and that version remains a very visible part of the city.

The pattern tends to skew younger. Couples in their early twenties are more likely to go all-in on matching looks, while couples in their thirties tend to express the same sensibility through smaller, less conspicuous details. Age doesn't make it disappear, it just makes it quieter.

Couple rings are the most classic form of this culture. After dating for a certain period, getting matching rings is a well-established tradition in Korea, and department stores and online platforms often dedicate entire sections to them. Unlike an engagement ring, a couple ring doesn't signal a commitment to marry — it signals that two people are together.

Anniversary Culture: Counting the Days

Why 100 Days Matters

Korean couples count anniversaries differently from most Western couples, who typically track things by the year. In Korea, the countdown begins on day one of the relationship, and the 100-day mark is treated as the first significant milestone.

The origin of the 100-day anniversary isn't entirely clear. One possible connection is to baeil (백일), the celebration Koreans traditionally held when a baby reached 100 days old, marking the point at which the infant was considered to have survived the most vulnerable early period.

Whether the couple's 100-day tradition actually drew from this is genuinely uncertain. It may simply be that 100 is a round, satisfying number.

Either way, the practice is real and widely observed, typically involving gift exchanges, a special dinner, or a couple photo shoot. Some couples plan weeks in advance, booking a restaurant or a photo studio slot the moment the date starts approaching.

The Full Calendar of Korean Couple Anniversaries

Beyond the 100-day mark, Korean couples track a series of milestones:

• 100 days: the first significant marker, usually with a gift exchange and a special dinner.
• 200 days, 300 days: some couples continue marking 100-day intervals beyond this.
• First anniversary (365 days): the largest annual milestone, often involving travel or a planned event.
• Second, third anniversary and beyond: tracked annually.

On top of relationship anniversaries, Korea has developed a calendar of commercial couple-related holidays:

• February 14, Valentine's Day: women give chocolate to men.
• March 14, White Day: men give candy to women.
• April 14, Black Day: single people eat jajangmyeon (black bean noodles) together, a semi-joking tradition for those without a partner.
• November 11, Pepero Day: couples, friends, and family exchange Pepero snack sticks, whose shape resembles the date 11/11.

Why Couples Keep Doing This Despite Knowing It's Commercial

Most Koreans are well aware that several of these dates were created or amplified by commercial interests. That knowledge doesn't necessarily reduce participation.

The logic tends to run: the date is a convenient excuse to express something that might otherwise go unsaid. What matters isn't the holiday itself, but the fact that you remembered, and did something about it.

Digital Couple Culture: KakaoTalk and Photo Studios

Couple culture in Korea extends into digital spaces, particularly KakaoTalk, the messaging app that functions as the primary communication platform for most Koreans. Many Korean couples set each other's photos as their profile picture, or upload a shared photo as a couple display.

This is visible to everyone in their contact list and functions as a soft announcement of the relationship. Scroll through a Korean person's KakaoTalk friend list and it's common to spot several couple photos in a row, tiny thumbnail evidence of who's currently together.

Couple photo shoots are another well-established tradition. On significant anniversaries, particularly the 100-day mark and the first year, many Korean couples book sessions at photo studios that specialize specifically in couple photography.

These studios are widespread in Korean cities, especially in areas popular with young people. The photos tend to be kept as private mementos rather than posted publicly, though social media sharing is increasingly common.

How This Has Been Changing by Generation

Couple look and anniversary culture remain genuinely common among Korean couples, but the intensity varies by age and personality. Among Koreans in their early twenties, the full version of these practices is most active.

Among people in their thirties, the approach tends to be more understated, expressed through smaller gestures rather than coordinated outfits or elaborate anniversary plans. There are also Koreans who find couple look unnecessary, and couples who don't track anniversaries at all.

Common Misunderstandings

• ❌ Myth: Matching outfits are about performing for other people or showing off.
• ⭕ Reality: For most couples, it's about the shared act of choosing together, not how it looks to outsiders.
• ❌ Myth: Since dates like Pepero Day are commercially driven, Koreans don't really care about them.
• ⭕ Reality: Knowing a holiday is commercial doesn't stop most Koreans from treating it as a convenient, welcome excuse to show they remembered.
• ❌ Myth: Every Korean couple does full matching outfits and elaborate anniversary events.
• ⭕ Reality: Plenty of couples, especially in their thirties, express the same sensibility through much smaller gestures, and some skip it entirely.

What Koreans Actually Say

The lines below aren't direct quotes from real interviews — they're representative of the kind of language Koreans commonly use in these situations.

Foreigner: "Isn't it a lot to plan matching outfits every time you go out?" Korean: "It's not really planning, it's more like picking something together." (thinking: it's honestly more fun than it sounds.)

Foreigner: "Do you actually care about Pepero Day, or is it just marketing?" Korean: "I know it's marketing. I still want my box of Pepero, though."

Foreigner: "What happens if you forget the 100-day anniversary?" Korean: "Let's just say you don't want to find out."

Practical Tips for Foreign Visitors

If You're Dating a Korean Person

The 100-day mark is worth noting in your calendar, even if your partner hasn't mentioned it. Bringing it up first, even just asking "when is our 100 days?", reads as a sign that you're paying attention. The gesture matters more than what you do with it.

On couple look, read your partner's energy before assuming. Not every Korean person wants to coordinate outfits, and asking first is always more considerate than assuming. If your partner shows interest, starting small, like the same color hat or matching phone cases, is a more natural entry point than full coordinated outfits.

If You're Just Observing

When you see a Korean couple in matching outfits on the street, the most accurate reading isn't "that's a lot." It's "those two put some thought into going out together today."

The motivation behind it is straightforwardly affectionate, not performative. Once you see it that way, it stops looking strange and starts looking like exactly what it is.

Conclusion: Love That's Counted and Worn

Korean couple culture, matching outfits, tracked anniversaries, couple rings, and photo studios can look like a lot from the outside. But the impulse underneath it is recognizable across cultures: wanting to mark that you're with someone, that you remember the days, that you thought about them when you got dressed in the morning.

Korea simply has its own specific language for expressing that. Once you understand the vocabulary, it stops reading as unusual and starts reading as what it actually is: a set of ordinary ways of showing up for another person.

If you're in a relationship with a Korean partner and the 100-day mark is coming up, now you know.
