Japaneses do not really wear so different style than foreign. Maybe with a "asian touch" haha. Right now, babydoll-dress(is it called like it) is really popular! Because it's so easy and it's so hot!
I like such brands like;
mocha, Myfashion, Aya Ori shop wich has really cute belts and accessories!, ROOTOTE wich has cute bags, SCOPY, Milly Molly Mandy wich really awesome Vivienne accessories, Romantic Standard, Serendipity, G2, Emily Temple Cute, Hanjiro Harajuku, and so on.~ You should look out for them.
Some of those are really cute, and maybe they do not suite your style. But many woman in 20~30 use them.
