Hmm. you seem desperate lol.
Uhm. I don't know if you know any of the Korean brands.
The Stori // located at Wangsimni Station Exit 8
Roi Arts // located around Sangsu Station Exit 1 (walk towards Hongdae)
Liful // located at Apgujeong and Anyang
Ikonz // located at Sinsa (i think)
Kasina is the easiest to find with locations at Myeongdong and Apgujeong.
Zzubo has a decent collection too. They are at Apgujeong as well.
And I'm sure you know Stussy is at Apgujeong too.
I suggest just walking around and looking.
I don't suggest anything from Dongdaemun. They had some SBs and they were straight up fakes. I compared them to my pair.
