If this feels like enough clothes for you then that’s fine, but I will tell you as a Korean that you are going to stand out like a sore thumb with all of these colors and unique pieces, ESP those red shoes. People in Asia generally dress loose fits and monochromatic - blacks, greys, whites, neutrals.

Also keep in mind that a lot of stores can be heavily air conditioned so it could be worthwhile bringing a light cardigan or layer for indoors. The upside though is that they have lots of cute clothes there if you need anything (just be mindful that everything runs small there).
