idk too but (as a kpop and kdrama enthusiast lol) ive noticed that wearing school uniform in an amusement park is a popular activity among koreans both teens and adults alike cos it's giving them exciting and nostalgic vibes xD
While studying there I did it with my friends and honestly it was such a fun experience! It felt like we were a on a field trip (▰˘◡˘▰) You can even decide whether you want to wear the full uniform (female or male version) or just the pants or the blouse I highly recommend it !!
wearing a school uniform at an amusement park in south korea is definitely a must (≧∀≦)
