Check Jadon's posts here, he has one on instagram which I think could help you with the vibe you need when messaging girls outside of dating apps (assuming you aren't doing this on a dating app). You're asking a lot of questions and being friendly without teasing and being clear about your date. Your questions are good if its in an actual date but not over text since you'll end up the cute nice guy messaging friend to her. I won't get my hopes high on this. Just ask her before the date day if she picked out something cute for tomorrow and see how it goes.
