Halloween // Halloween themed wedding ideas needed

TL;DR Title says it all, be as creative as you want!

I figured this is the best place for this. I'll probably post this in r/wedding too eventually but y'all will be way more creative.

He hasn't proposed yet but we've always talked about getting married basically from day one. How can you not when he pays $250 to get your car out of the inpound and not ask to be repaid * on the first date *!? I've always been a hopeless romantic but never truely believed in love at first sight and I've always tried to stay away from getting married right away which is why we are about to celebrate 4 years. But at this point, he mine and I'm his. We just need to save up for the ring.

We are going for a celtic Samhain wedding but there will be elements of Halloween involved. Such as the stage having spider webs hanging around it and Jack-o-lanterns lining the chairs. It'll be outside at twilight, I live in the American south so it'll be cool but not freezing thankfully.

There will be a bonfire The bride's maids and groomsmen will have swords and I'm thinking of them doing a Saber arch but I'm not active military nor is he and I'm worried that'll be disrespectful.... I just thought it would look cool. Maybe wands or staffs instead? Spiders and spider webs Jack-o-lanterns

What else can I do?
