How should I ask her about her Halloween plans?

This girl and I have been talking for over a month, we actually went out once but we cooled off since we both had recent breakups

We still talk a lot and I know she likes Halloween stuff, and I've been to her apartment a few times and is happy when I'm around

Her parents are staying with her this week and she's told me she focused only on that when they're here, but with Halloween coming up soon I kind of want to make that a date, or at least before Halloween have a date so then we can spend Halloween together

Appreciate any advice
