Seriously, you're just going to have to do as best you can to emulate whatever star or band you want to emulate... You have about as much chance of running into a stateside Visual store (and these are even rare in Japan, if they exist at all), as you will of finding a duplicate of something like Baby The Stars Shine Bright.
You're just going to have to wing it... Now, my question is... where are you going to wear this type of attire!?
