Ayu cosplay at concerts? (+help?)

[alternarist]

i wouldnt say they are silly. I would say they are passionate as they are willing to spend so much time making the costume or so much money buying the costume. but if they were to wear something like Microphone PV's outfit, i would think that it is not practical as it's bulky and take up a lot of space. How to enjoy a concert in this way??

But i did see people cosplaying In The Corner AT2009. Simple and sexy!! or u can cosplay Rule AT2009..
