I really liked Takane singing it, she sounded good. I'm not sure if I like the puchimasu thing, though; just...to me, when they have it on their head it looks like they're trying to balance it.
Opinion might change after I watch the preview a few more times, but Azusa's segment (imo) looked like her dance was a bit stiff for trying to keep it from falling off her head XD
If I had the capability to buy the outfit, though, I would in a heartbeat!

It kinda sucks that the boots are DLC too, though. The outfit looks better with them...
