Honestly, I've had a phase where I (embarrassingly) really wanted to dress up like them here in here. So I did, when I was about in the sixth grade or whatever, I'm literally now typing this while thinking about all the stupid outfits I put together which I thought were "cool" and "kawaii". Just the thought of a sixth-grader-wearing-rainbow-tutus-and-neon-leggins makes me want to push the-sixth-grade-version of myself down a set of stairs. Up until now, I still think they're absolutely amazing, since they don't really follow trend, they just wear what they want, and proud of it.
Here are some of a few, and more subtle, pieces that you can wear, and mix with plain, classic key-pieces such as basic t-shirts and a nice pair of jeans which can never go wrong with anything. Or you can go all out, the choice is up to you! People will definitely be staring at you, so just walk proudly and just wear what makes you happy. If you can't go to Harajuku, take Harajuku here with you, and with your very own spin!
