Hi, Alicia! Thank you for bringing your great question to the Disney Parks Moms Panel!
First of all, let me start by telling you that you're about to have a FANGTASTIC time at
Mickey's Not-So-Scary Halloween Party. Your night will be even
better because you're planning, so congratulations on that!
It's a pleasure to tell you that costumes are joyfully encouraged at Mickey's Not-So-Scary Halloween Party. There's something spookily surprising about visiting
Magic Kingdom Park when Guests are in costumes, and I'm sure you'll love it.
There are
specific rules that Guests must observe, though, and
masks of any kind are prohibited. I hope this information encourages you to find the perfect costume option that will grant you a worry-free night. You can
find some inspiration on the Disney Parks Blog. That's where I got
my ideas for my next Mickey's Not-So-Scary Halloween Party costume.
If more questions pop up before your spooky night out, please, stop by! We're always here to help fellow Disney souls meet their squad ghouls!
May the magic be with you,
Julie
