Bodyline.co.jp has alot of cheap lolita clothing. For ouji, you can get your blouses and shoes here, but they only sometimes have ouji-appropriate bloomers or pants.
For gyaru clothing, you can easily create an awesome gyaru outfit with clothing found at your local mall... But for actual gyaru brands, Yesstyle.com just started carrying Ma*rs, Golds Infinity, Liz Lisa, Glavil and a few other brands. They ship worldwide and always free shipping.
