How South Korea’s military t-shirts became a fashion statement

Once reserved for soldiers, “R.O.K.A” apparel is now worn by teens, K-pop fans, and families—at home and abroad

On hiking trails and in gyms across South Korea, K and his wife, both in their 50s, have been struck by a curious new sight: young men and women in black T-shirts boldly emblazoned with “R.O.K.A” and “KOREA ARMY,” the Taegeuk flag crisp on the sleeve. Shorts complete the ensemble as they lift weights or sprint on treadmills.

“When we were young, we tried not to stand out as soldiers,” the husband said. “Now, even on leave, they train proudly in uniform.”“And there are so many female soldiers now,” his wife added. “It’s reassuring to see.”

On a recent vacation in Southeast Asia, the couple spotted Korean families in matching military tees. “Are they a military family? But where are the boys?” they wondered—only to realize the children weren’t enlisted. At a local waterpark, elementary through high school students wore the same shirts. “Where did you get that?” someone asked. “It’s trending online,” came the reply.

They had stumbled upon South Korea’s unexpected fashion phenomenon: the “R.O.K.A. tee” craze. R.O.K.A—phonetically representing the Republic of Korea Army—has transcended the barracks. Millennials and Gen Zers wear them as workout gear, pajamas, and couple’s shirts; middle-aged Koreans coordinate them for family gatherings or alumni reunions. Among teens, the tees have become coveted “influencer items,” tucked under school uniforms or matched as class shirts, with popularity even trickling down to elementary students.

The apparel comes in every conceivable iteration: black, white, digital camouflage, hoodies, fleece jackets, shorts, and lined pants, making it possible to rotate R.O.K.A. gear year-round. And the trend isn’t limited to the army: Air Force, Navy, Marines, and elite UDT shirts are also catching on.

For actual soldiers, the craze is almost paradoxical. “Wearing a R.O.K.A. tee doesn’t make you look like a soldier anymore,” some joke. “I don’t know why civilians are wearing them.”

The trend traces back roughly a decade to online communities of women waiting for boyfriends serving in the military—so-called “gomshin.” PX-issued soldier shirts given as gifts sparked couple photoshoots, creating a viral template. Military parents soon joined, wearing the tees in solidarity with their sons. Demand has grown so high that knockoffs abound, though authentic PX merchandise remains the best-seller.

Globally, the craze has been amplified by the return of K-pop idols like BTS and SHINee from military service. Overseas fans have embraced these uniquely Korean military symbols. For BTS fans—whose fandom is called ARMY—the connection is almost obligatory.

Fans cite comfort and affordability as additional draws. At roughly 10,000 won ($7.50) and crafted from breathable, stretchable fabric, the shirts are ideal for exercise or casual wear. Young women wear them at the gym to project confidence; teens prize them as a brandless, unifying display of Korean identity.

Ultimately, the R.O.K.A. phenomenon is less about fashion than pride. It is a celebration of Korea itself and of those who have defended it—a rare style that allows wearers to honor the nation with a T-shirt, anywhere in the world.
