It's a great addition to her other outfits, being more stylish and showy. Tentatively I'd rate it just behind her OG one, if not higher. I think it works well both with or without the jacket, but I prefer the latter because of the sleeveless+gloves combo. The way the booba is superimposed over the jacket may look weird but I think it's better than when the opposite happens and the jacket flattens what's under it. And of course the hair is perfect.
She said something during the reveal about wanting something more suited for karaokes and such, and it shows, reminds me of the "cool" outfits you see in idol games. According to Pochi, the text on the right of Reine means "many customers come constantly"+"luck will improve and happiness will come", basically Reine's "JOINDA" schtick in japanese proverb form. The text on her left reads "beware of the rampaging bird".
Even if I guessed wrong with the cat ears, I feel vindicated knowing that someone else though her silhouette looked like Fubuki.
