Join in On the Fun: DIY Halloween Costume Ideas for Adults

Just because Halloween is most often geared towards kids and Trick or Treating is talked about like the biggest priority of the season doesn’t mean adults can’t get in on the fun too! We adore making costumes and setting up parties and such for our kids as Halloween approaches, but we also like getting festive and celebrating right along with them, so we’ve been on the lookout lately for different kinds of DIY costumes for adults that we can put together ourselves and wear to our own parties or alongside our kids as we walk them around the neighborhood on the 31st.

Just in case you’ve been searching for DIY Halloween costumes for yourself as well, here are 15 simple and creative designs, tutorials, and ideas that we’ve come across in our search so far!

1. Adult Minions costume


If your kids are even half as obsessed with The Minions as ours are, then we have a feeling this idea might be right up everyone’s alley! DIY Inspired guides you through the process of partially making and partially assembling a funny Minion costume that will make just about any kid you encounter on Halloween very excited indeed to see you.

2. Adult Little Red Riding Hood cape


Are you actually quite good at sewing and prepared for something that’s a little more challenging, like creating a full garment from scratch? In that case, we’d absolutely suggest taking a look at this pattern and tutorial outlined step by step on Fleece Fun in order to make yourself an awesome hooded cape that would be useful for several different kinds of costumes. Our first thought is Little Red Riding Hood, but you could also use it for something more pop culturally current, like Game of Thrones characters!

3. Bun in the oven costume from a cardboard box


Have you actually been searching for a site that can give you some ideas and a bit of guidance online because you’re expecting a baby soon, so your costume making process for yourself is a little different than what you’re used to this year? Well, if you’ve ever been a pun or wordplay fan, we’d definitely suggest taking a look at how A Crafty Spoonful made this funny “bun in the oven” craft that actually includes a miniature DIY bread oven as part of its appeal!

4. Simple adult zombie costume


Are you actually a little bit pressed for time and resources right now because you were invited to a party last minute? Then maybe you’d do better with a DIY costume idea that lets you destroy old things you already have rather than trying to buy new supplies or make something from scratch! This simple streetwear zombie idea featured step by step on The Rebel Chick is the perfect example of what we mean.

5. Adult pineapple costume


Perhaps you’re actually a huge fashionista who always tries to incorporate style into your Halloween costume because you enjoy looking your best? Then we think perhaps you’d get along a little better with something like this funny pineapple costume featured on Studio DIY! You can choose whatever bright yellow outfit you pleased for the main body, but they still teach you how to make your own pineapple stem out of paper.

6. No-sew adult Winnie The Pooh costume


Even though we’re quite experienced at sewing, sometimes no-sew Halloween costume ideas are our favourite. That’s because they’re usually rather funny or kitschy, and because the easier our outfits are, the more we have time to make! We think this Winnie The Pooh family costume idea outlined step by step on Moms and Crafters is rather adorable indeed.

7. Adult Merida costume from Brave


Even though you’re no longer a kid, is your favourite part of Halloween still using the holiday as an opportunity to transform yourself into a Disney princess, just like you did when you were five? Well, we certainly can’t say we blame you! That’s why we couldn’t help including this fantastic DIY adult Merida costume featured in detail on Love Maegan.

8. Adult Rubik’s cube costume


Have you always rather preferred the big, funny costumes that really catch people’s attention and make you stand out because you’re dressed like some kind of funny homemade object? In that case, we’d definitely suggest taking a look at how The Benson Street made this awesome solved Rubik’s cube outfit! You could also scatter your colours and make yourself an unsolved cube instead, if you prefer.

9. Quick and easy adult black cat


Are you the kind of classic Halloween character lover who adores being something simple and recognizable, just because they’re cute and familiar? Then we’d absolutely suggest taking a look at how Style Domain put together this very easy (but fun to wear) black cat’s outfit in just a few simple steps!

10. Homemade adult Lego piece costume


Just in case you’re still totally into the idea of making yourself into a funny oversized object in a really crafty, fun way but you’ve already tried the Rubik’s cube before, here’s an awesome alternative for you! Check out how Dream A Little Bigger used a cardboard box and some old, round plastic containers to make the shape and then paint it whatever colour you please. We like the idea of going out with a whole group of friends, each one of you dressed like a differently coloured Lego piece!

11. Awesome homemade spider web cape


Perhaps you’re the kind of costume wearer who prefers to make one really impressive spooky piece that you’ll have a lot of fun wearing, even if it’s not a character or specific theme, rather than assembling something very simply or throwing a quick DIY idea together? Well, if spider webs have ever been a Halloween element you appreciate, then we think you just might be the perfect person to give this awesome webbing cape outlined step by step on Delia Creates a try!

12. Cereal killer costume


Just in case we really caught your attention with the idea of making a costume that’s “punny” or a play on words in some way but the idea we showed you before doesn’t work for you since you’re not currently pregnant, here’s a hilarious (and rather easy to make) alternative! Check out how Huffington Post used plastic knives and mini cereal boxes to turn themselves into a “cereal killer”.
