Halloween is October 31st, and it has been October 31st every single year without exception, which makes the annual "I don't have a costume" panic both completely avoidable and somehow universal. Here's the thing, though: a last-minute costume doesn't have to be a bad one, and a low-effort costume doesn't have to be boring.Some of the funniest, most talked-about costumes at any party are the ones that took twenty minutes and a single Amazon order to pull together, because a genuinely good idea executed simply will always beat an elaborate costume that nobody quite understands without an explanation. This list is proof of that. Every costume here is easy enough to put together without losing your mind in the process, funny enough to hold its own at any costume contest.#1 Slap On A Pitbull Bald Cap , Throw On Some Sunglasses, And Suddenly You're Mr. 305 Himself Standing In Someone's Living Room Asking If Anyone Wants To Go To MiamiReview: "Excellent bald cap kit, 10/10 would purchase again!

I am a 300+ pound individual and it fits well. With this costume and the fart machine I got, this Halloween will be a gas." - Albert HellerBuy Now: amazon.com#3 Nobody At The Party Will See A White Poodle Mask Coming And That Is Precisely The Energy That Wins Costume Contests Full Of People Who Spent Three Weeks Planning Something Far More ComplicatedReview: "Just ordered this for my 10 year old for Halloween. He scoured Amazon for costumes and decided on this. It's pretty much the most realistic dog mask I've ever seen. Which makes it simultaneously creepy and hilarious. I put this picture on Facebook and most people thought it was a real dog on first glance. The one negative is that it's not that easy to see out of. I'm pretty sure he will fall at some point on Halloween. Aside from a possible injury on someone's front porch this mask is a winner. It looks the best with normal every day clothes. Not sure why. It feels a little "Purge'ish" but I mean, it is Halloween. I tried it on and it fits me too. So kids and adults alike can partake in the fun." - EmilyBuy Now: amazon.com#4 Walking Into A Halloween Party Wearing Nothing But Regular Clothes And A Fish Mask Is A Power Move That Requires Zero Explanation And Somehow Gets Funnier Every Single Time Someone New Walks Through The Door And Sees It For The First TimeReview: "I had a hard time getting dates while wearing this.

There's a lot of porch goose costumes available that I just didn't really vibe with, or they were too expensive. Like yeah, I own a porch goose, but I'm not insane.
