Can you believe it is already the time of the year when pumpkins are being turned into jack-o-lanterns, horror movies are stealing the spotlight, and kids are preparing their trick or treat costumes  – and great costumes are needed.

Unicorns are usually more associated with magic than with horror, but there’s nothing wrong with having a magical Halloween rather than a spooky one! And – as you may read in our article “Different types of unicorns” – there are types of unicorns who show their dark side as well… 

Here are our suggestions for fun unicorn Halloween costume ideas for 2021. You can decide for yourself – trick or treat! Magical or spooky! Corn or Horn! Either way, there is a high chance that unicorns will rock Halloween in 2021. 

Halloween Unicorn Accessories: Sparkle With Magical WOW

Halloween does not have to automatically mean horror. You can always dress up with a little bit of hope and sparkle, and gather around you some magic and positivity that might otherwise be missing from the day – especially a day like Halloween. Luckily, unicorns always give us opportunities to spread joy, magic, and hope. They can also be pretty refreshing and unique during Halloween, a touch of something different to ghosts and ghouls!

Colorful Unicorn Wig with Silver Horn

1) This amazing and colorful wig falls somewhere between mystical and magical. It could be part of a lovely fairy tale, but at the same time it could complete the evil unicorn princess look – it all depends on the rest of your outfit and the make-up that you choose to wear with the wig.

A silver horn and silver ears will provide a mystical look and magical sparkle that can be seen from far away. It’s totally up to you – you could even do both to show your different sides, and change during the night, demonstrating who the real queen of costumes is!

Inflatable Unicorn Costume: for Adults as for Toddlers

2) To be the hero of the party and guarantee people’s attention, here is an amazing choice for a costume: Inflatable Unicorn. Move over Prince Charming: this really is the next level.

Princes on white horses are history. Princes on rainbow unicorns – they really are magical and extraordinary. They’re also funny, and I bet if there are prizes for the best costume, you can get yourself ready to grab one – or at least your unicorn can.

For those who want to match their kids on Halloween, here is the inflatable unicorn`s “kids’ edition” of a Prince Unicornizing on his unicorn. Ah, this is so cute and would be so much fun for the wearer and the people around them! 

Unicorn Head Mask: Easy and Effective

If you take Halloween seriously, you may even want to walk home with this mask on – I would find myself pretty frightened meeting this unicorn in a dark street at night –  unless it was Halloween of course, and then it might be a nice opportunity to update the IG story or cool TikTok.

Halloween Unicorn OutFit

Unicorn Costumes and Halloween For Toddlers

If you have kids in your family or you have little nieces or nephews visiting, Halloween, with its dramatic vibe, mystical decorations, spooky costumes and buckets of candy, might be the most eagerly awaited holiday among the youngsters. Some of them might not be so into horror over fantasy, so unicorns can be lovely companions for a kid-friendly Halloween, especially as more and more people are finding ways to link the two together.


Girl`s Unicorn Costume

19) There is a high chance that any little girls in your household might want to dress up as fairy-tale-princess-unicorns for Halloween and most of us just can’t resist those adorable costumes, with pastel tutu skirts, glittery horns, and even wings, making the children into the most charming little alicorns imaginable – like this unicorn princess fairycostume here

Moonlight unicorn halloween costume

20) There’s also a chance that they might want to embrace their spookier side and fit in with the general Halloween atmosphere – and possibly even try to frighten their parents. This is a costume for Moonlight Unicorn, who is pretty much the equivalent of Maleficent to the Fairy Godmothers. It has personality, it has drama, it’s definitely unicorn-y, and it would work perfectly for Halloween.

21) It is also common to meet skeletons on the streets, in shops and at school during Halloween, so your child could consider becoming a friendly “unicorn skeleton” for the night, and this costume would be perfect. Fun colors help to keep the costume bright and not too scary, but it’s still very clearly a skeleton – a friendly, colorful, and cheerful unicorn skeleton that comes out especially for Halloween.

22) Halloween might also be a great opportunity for kids to dress up as their favorite hero. Some kids might be into Ironman, some love Captain America, and Wonder Woman has her fans… but some kids just adore unicorns, and as in kids’ worlds creativity is limitless, this DIY hero costume would offer them a lovely opportunity to become a new hero with uniqueness and style. Design the cape yourself and involve the hero – he/she can save all the candies in the neighborhood with this outfit!

DIY Unicorn Mask

23) If you want a different look with a bit more DIY, this unicorn mask might be ideal. I think I would be pretty scared if I met this one in the streets alone after dark… It looks easy to fold up and I think it would be really effective to wear during Halloween. You could also use different colors or draw on it to make it unique to your child. You could even get your child to collect memories from friends on it to keep it as a reminder of that amazing Halloween when they dressed up as a unicorn. 

Trick Or Treating With A Unicorn Bucket

There is no real Halloween, for kids at least, without “Trick or Treat” going on, and that means no real Halloween costume should be without the sweets bucket. Think how magical it would be to see kids or send them on a candy hunt with a unicorn basket. Who knows, perhaps the candies inside the basket will transform and get some special powers from the unicorns protecting them? The kids certainly might think so! Halloween can have just as much magic as Christmas: anything can happen if unicorns are involved.

Unicorn "Trick or Treat" Bucket

24) This unicorn trick or treat bucket has the brightness and colors to balance out all those spiders and ghosts that will be around on Halloween. It looks bold, brave, and determined and will give the holder a dash of courage even if they are the shyest trick or treater.

26) To go back to basics, this plush unicorn Halloween Bucket is a mix of cute, soft and unicorns. It is totally adorable with unicorn eyes and round cheeks, but it still keeps the mystic Halloween vibes. It makes an adorable combo all in all, I have to admit.

27) Here is a costume/shirt that lets the child dress as a unicorn and gives them the perfect excuse to carry a regular pumpkin style jack-o-lantern bucket for sweets. I’m already imagining how much fun it would be to find a dabbing unicorn trick-or-treating outdoors.
