Costume party at almost 36 weeks pregnant?

We were invited to a friend’s Halloween-themed party, it’s about 45 minutes away and at 7pm and I’ll be almost 36 weeks pregnant at the time. They want us to dress up in costume, but other than that, it’s a pretty chill party.

We need to RSVP soon, but what do you think? FTM so I’m not sure if I’ll likely be miserable lol
