I think only in Seoul you can wear pretty much any high fashion look and people won’t look at you like some kind of weirdo like they do in Jakarta. Like for example, this short suit look. He reminds me of Thom Browne’s signature suit. This young gentlemen wear it complete with hat and suspender plus sandals (it was big fashion in Seoul at the time).
The result? Real fashion on street (well in this case at the train station), but you get my point.
