Help me prepare for Anime Midwest 2024!

Hi everyone, I've been struggling to choose between my two favorite character which is Chihiro "Sen" Ogino from Spirited away or Mitsuha Miyamizu from Your name. I was about to go to Anime Midwest 2024, and I couldn't decide what to wear. I was really excited and I prepared myself for this special day. My friends told me to dressed as my favorite character because it was a big day for us. I was about to see voice actors and panelists, and get to see how they performed. I Hope you guys attend as well.

Help me to choose on those two characters, so I can prepare myself on how should I act like those 2 characters. Thanks!
