Harajuku Anime ????

Fashion in general, I would recommend Paradise Kiss, Gokinjo Monogatari, Princess Jellyfish (more so in the manga). These are aimed at kids, but I like some of the fashion in these: Pretty rythem, aikatsu, pri para, and Heartcatch pretty cure! 

these is probably more,but this is all that I can think of.

there's an entire anime inspired by harajuku fashion and about fashion, self expression, and finding your own identity. it's called artiswitch and you can watch all the episodes here:D it's also an indie anime so go support it and spread the word!
