well first off check out this site
www.zozo.jp
I like to buy my clothes from there sometimes but i see ur not really going for fashion, ur going for style. Fashion and Style r two totally different things
This is Fashion
This is Style
Well for starters, do u live in a big city where u can have easy access to different sorts of name brands like NYC for example or LA. For me as a guy, i like to shop at high end fashion stores like famous friends nyc (diet butcher slim skin), Bloomingdales on 59th, NYC for jeans such as citizens of humanity, sevens for all mankind, rock and republic, true religion, cheap monday(Good brand if ur looking for a visual kei style and they arent exactly "cheap"), APCs, etc...
Good Visual Kei brands that u will probably never find in the usa
-sex pot revenge (cheapest brand on the list i am giving u now(not exactly cheap either))
-H.Naoto
-Green Lizard
-Vivienne Westwood
Good Japanese brands that isnt Visual Kei that u can definetly find in the USA but they r highly fashionable and only for the exculsive
-Evisu
-Red Monkey Company
-Samurai Surfer
-Ksubi
Plus alot of japanese people also like to wear american brands like
-diesel
-J Brand
-True Religion
-Antik Denim
-Joe's Jeans
If You are looking for the Oshare Kei look
-Bathing Ape
-Billionaire Boys Club
-Ice Cream
-Training Camp
-Tokidoki
-kidrobot
Well thats all i can say for now cuz i g2g or else i wud've added more to ur answers but ill post more info about brands when i get home
Keep in Mind that the brands ive given u usually go no less than 80 usd for a shirt and no less than around 150+ for a pair of jeans except for tokidoki shirts which u can get for around 30 usd.
So basically unless ur willing to Go to Pac Sun or something to put together a visual kei outfit which i would never do because i still have my own personal dignity and respect. Then i suggest u try the site but be prepared to shelf out dollars in the hundreds if not thousands
