It's easier then here, but it is hard to find. The thing is Korea was collinized by the Japanese and horrible things were done to the people. Those feelings still linger so Japanese things aren't really promoted.
Once I arrive I'll give detailed clothing options and photos.
If you don't care so much about brand then it's easy to find gyaru style clothing. If you send me pictures of the look you like I can introduce you to some korean brands.

Geo, a korean lense, is my absolute favorite to use. They are very comfortable, and GEO is a medical brand with a special checking system.
I'm stocking up when I go! XD
