Can anyone list any popular Asian (Hong Kong or Japanese brands) clothing brands? (such as G2000)?

Answer 1

This is a link that will take you to a page full of clothing brand links. You might not be able to read Japanese words unless your Windows is configured to display Japanese but you can still click some of links right next to small Japanese icons to see Japanese brands.
