It’s easy to find hanboknam shop, which is located at exit 4 of Gyeongbokgung station. If you are bringing along kids with stroller, there’s an elevator near exit 4. I chose the themed hanbok where there are more choices of “blinky blinky” dress compared to traditional hanbok of simpler choice. The staffs are super helpful. I went in the morning and weekday to avoid crowd. With 2 kids, I chose 2.5hr of rental where I had plenty of time strolling around and taking photos, no rushing at all. Kids hanbok is located at upstairs.
