Halloween // Halloween party

Hi guys! For a bit of background I grew up in THE house of my neighborhood so I have always loved Halloween First 2 years in my home (albeit pandemic) I learned my neighborhood does not do Halloween. Like at all.

So I decided to throw my very first Halloween party this year. I have my costume ready(purple fairy) , and am trying to figure out my husband's but do you guys have Any advice on invites, decorations, dos and donts? Thanks!
