I did think it was a bit sus that she was allowed a +1 and took nobody with her because people would obviously assume she'd take Flossie or Lewys. Honestly if it was me in her position I'd love the idea of being able to let someone else in on such a cool experience. She could have taken her sister even, or tbh her mum! What a wonderful thing to be able to share with someone, but she's too busy trying to worm her way into being a socialite so everyone around her has to be "cool" or influential I guess.
