I usually come up with a conceptual costume that doesn’t involve a lot. One of my favorites is to put a toy monkey on a string so that it hangs down my back. Another is using a marker to put 665 on my face. That 665, so close. I haven’t thought one up this year, it’ll come to me. So what is everyone going as?
How about 667? Always on the cutting edge, ahead of your time.
I am going as the scariest thing the people around me know.
Me. 
In Ireland we didn’t use to dress up for Samhain. In Scotland the Guisers did, but not the rest of us. Our tradition, in both countries, was fireworks, and parties with things like ducking for apples and eating a jammy-piece on a string.
Trick-or-Treating hasn’t caught on in England. We sometimes get a few enthusiastic children with apologetic minders, but they don’t go far afield. If you are more than two-hundred yards from anyone with young children, you are unlikely to get trick-or-treaters. We haven’t had any for the last two years. We do lay in a supply of sweeties - sorry, “candy” - but it was untouched.
I am having people around for a small firework display on Monday night. There will be mulled wine. I’m pondering the scariest features I can carve into my usual two pumpkins. (We don’t like to overdo things.) I think the thing that’s likeliest to scare the neighbours is the word “POLICE” carved into the pumpkin. I am certainly tempted…
Will you be able to get the faces of all three of them on one pumpkin?
Fair Point. I might have to confine it to “Police Sting”…
You’ve prompted a better idea though. I could do Katie Price, using three pumpkins…
I’m going to take my whistle out and pretend to be a musician.
I can’t remember the last time I wore anything more elaborate for Hallowe’en than my jack-o’lantern hat, but here’s my daughter Becca and bf Jason from last week:
(this will be obscure unless you’re familiar with this viral youtube clip and know that Becca is a turtle.
Olivia and her bf Brian usually come up with excellent costumes. Last year they were Princess Daisy and Luigi, and a couple years earlier Pikachu and Ash. Olivia usually makes this stuff herself.
You raise 'em right, emm!
We’re going to a Halloween murder mystery party tonight. I have the part of a swamp monster (I got a ghilli suit for that), Tom is tje serial killer (hockey mask, machete, etc.)
On Monday I’ll have my usual witch costume on.
In some places it has really taken off. I know loads of people who now loathe Halloween as they get over-run by kids on the prowl for free sweets. I’m lucky, I live on a quiet little lane that nobody comes down but on the local estates it is apparently a free-for-all at times.
As for me, well I’m a miserable old scrote and won’t be dressing up at all.
Here in the States things have moved along and Halloween is definitely not just for children any more; adults really get into it, and I have seen some very creative getups, from the brilliantly silly to some so disturbing as to elicit much comment. But of course that would be the intention. Adult Halloween costume parties and pub crawls are now commonplace, and it seems as if everyone talks about what to wear. You get some great people-watching at this time. Some of it not so good. But, that’s how it is. The main thing is the fun of being big grown-up kids.
I’m wearing scrubs, a surgical cap and mask. Alas, I’m on OR call on Halloween… Any blood you see on me will be real 
We take all our creativity out on our pumpkins, then I light them up with strobe flashlights, that way I can bake them the next day. Unfortunately some of the younger children get a little scared of these pumpkins so I usually stand outside where they don’t have to pass the pumpkins on the way to the front door. The older kids love them, I usually carve my pumpkin’s mouths to look something like an Anoplogaster cornuta, it’s very effective with the strobes. Of course we can’t go punkin chuckin this year but I’m teaching one of our nephews how to build a catapult so maybe by next year.
I can’t believe you assumed we’d be OK with
“ducking for apples” and “jammy-piece”, but
felt you had to clue us in on “sweeties” 
Better than the ER, I guess. I hear that’s
a real nuthouse on Halloween.
I was going to go as Dr McNinja from the appropriately titled “Adventures of Dr McNinja” webcomic. Unfortunately my Halloween plans were cancelled, so no dressing up for me. Oh well, there’s always next year!
During Halloween we used to “bob for apples” when I was a kid. You never did that?
There I’m clueless. Makes me think of the back-flap on a union suit, kind of.
I admit was tempted to chime in with, “…as in, tarts?” 
My wife thinks this is going to be Lucky’s costume this year.
This dog used to unwittingly reveal to us the kids from the neighborhood from the kids who were crashing the neighborhood. She totally loved Halloween and would run around like a crazy dog when kids arrived. The kids from outside the neighborhood would freak. The kids from the neighborhood would just say, “Cool costume Dot.” She got a new costume every year and kids would actually ask her before Halloween what she was going to wear. They’d knock at the door and see if she could come out and play. I don’t think either she or the kids realized she was a dog.

Hi Nanohedron
A jammie piece (or jeely piece) in the Haloween context is a slice of bread liberally spread with jam or jelly (as the case may be) that was suspended on a piece of string and you had to try and eat it without using your hands. Great fun for the kids and lots of washing for the mums the next day 
as they got absolutely covered in the jam/jelly.

Ah, we did have something similar, but different: an apple (again) would be suspended on a string, and a boy and a girl on opposite sides of it had to try to eat it, both at the same time, with hands behind their backs. Naturally it was great sport and hilariously grotesque: since apples hanging in midair are not obedient things, most of these underage couples would wind up clumsily planting their mouths together more than once, to the hilarity of everyone else. Usually the boys pretended to hate it until after a certain age, and then things could get interesting, if predictable. So of course the game kept its appeal for all ages.
I don’t remember what name we had for that farcical little forced-courtship ritual; something brilliant like “apple on a string”, probably.
