Can anyone enlighten those of us who are not in the know? The tag info doesn't really explain...
In the old pokemon anime, Misty/Kasumi wears this outfit during a performance with her sisters (it's been a long time, so I can't explain the episode in detail). As for why it's being mixed with "Happy B-day wishes", I don't know; it's probably just a phase, like they do when something in fashion becomes trendy.
Honestly, I wondering more on whether we're tagging it as cosplay of the pokemon or of Misty. Might be a while before I get that answer, though. Copyright issues tend to take some time in the courts ;)

I thought she was working for a magician. (I forget why.)
