Harry Potter Costume Ideas for Beginners

For people who don’t feel like dressing up that much or for people who want to go all out. Check out the Harry Potter costume ideas below and tell us which one you would wear at the next cosplay contest!

There’s no shortage here of characters you can be, since some of the most famous Harry Potter characters are loyal, brave Gryffindors.

1. Harry Potter

You can easily buy an adult Harry Potter costume online, and if you’re the kind of person who needs their children to also be HP fans, buy them a Harry Potter child costume as well, so you can match.

If you want to be Harry, you just need some robes, a pair of round glasses, and a wand. Not that high maintenance, right?

Start Shopping

Shout out to: Kevin Goulet for going the extra mile

2. Ron Weasley

If you prefer Ron, it’s even easier. Just dye your hair red if you dare. Wigs are for weaklings. However, if you want to portray Ron from the beloved Harry Potter fanfiction story “The Champion's Champion,” go online and get yourself an oversized chicken costume! It is a bit niche, but the connoisseurs will know immediately you are into some heavy Ron bashing and overall entertainment!

Start Shopping

Shout out to: Hugo Oliveira for the uncanny resemblance to our own Ronald Bilius Weasley.

3. Hermione Granger

Hermione is another obvious choice for a Gryffindor that’s really badass. A Hermione costume is easy to find, and bushy hair is a must. If you read the fanfic story The Green Girl, wearing a Slytherin costume on a Hermione impersonation will definitely make some of your Potterhead friends squeal with joy!

Start Shopping

Shout out to: Anna the Adventuress for all the SPEW feels

4. Professor Dumbledore

Who can forget the iconic beard and snazzy robes Albus Dumbledore used to wear? If you go for a Dumbledore costume, don’t forget the attitude: “Did ya put ya name in the Goblet of Fiyah?” On the other hand, you can try the “find light in the darkest of times” attitude. Everybody needs a little positivity and optimism right now.

Even better, go for a young Dumbledore who apparently favors sexy suits to eye-catching robes.

Start Shopping

Shout out to: Dumbledore UK for the incredible dedication

Let me start by saying I’m a Slytherin, so I maaay be biased, but a Slytherin costume is clearly the best way to go when brainstorming Harry Potter costume ideas. You may not love Draco Malfoy, you may totally despise Lucius, or never fully understand Snape, bot nobody can deny the Slytherin their ambition, intelligence, and competitive spirit.

5. Draco Malfoy

As the hero’s arch-nemesis throughout the books, Draco is one of the most cosplayed Harry Potter characters ever. Just make sure that when you cosplay Draco to pronounce the word P-p-p-potter with the oomph Draco uses in the movies.

Start Shopping

Shout out to: Procerperficio for that gorgeous hair

6. Snape

Are you ready to bewitch the mind and ensnare the senses? We hope so! Who hasn't dreamt about having Snape’s fabulous hair at least once in their lives? Pair that with some dark robes and a posh accent and you’re good to go. Don't forget about Snape's wand, one of the most mysterious of them all!

Start Shopping

Shout out to: luke_iezzi for the attitude

7. Bellatrix Lestrange

A personal favorite of mine, Bellatrix demands respect. Buy a Bellatrix Lestrange costume and use her wand to scare off little children, just like Helena Bonham Carter does. I am not sure what advice to give you about her hair, but I'm sure you'll think of something!

Start Shopping

Shout out to: Kelsey Ellison for pretty much everything

PS: I cosplayed Bellatrix at East European Comic Con 2019. Follow me on Instagram at @lauraandreeaa to see how it turned out.

8. Voldemort

A true classic, Voldemort is the character we all love to hate. You might think the lack of a nose would make people stay away from a Voldemort costume, but you’d be wrong. If you get the Voldemort movie version's accent, you are good to go!

Start Shopping

Shout out to: Pietro Civera for acquainting Voldemort with modern technology. Shout out to the make-up artist who helped make this happen, Alessio Morando.

Show your house pride parading around in a Ravenclaw costume for the ages. Since we are here, let us know which is your favorite Ravenclaw character! And, speaking of characters, which is your favorite superhero costume idea you would like to try this year?

9. Luna Lovegood

Ah, how I adore Luna’s character! She’s wonderfully quirky and sweet, and we should all aspire to be more like her, starting with her outfit. If you ever see invisible animals, it means you are channeling your inner Luna in more ways than one!

Start Shopping

Shout out to: Anastasya for the attention to detail

10. Cho Chang

Another Ravenclaw people love to dress up as is Cho. If you can pull off the brooding look, there isn’t much else you need to worry about. Except maybe your relationship with Cedric…

Start Shopping

Shout out to: The Artist Librarian for being the perfect Cho

11. Gilderoy Lockhart

Professor Gilderoy Lockhart might not be one of the brightest minds of his generation, but he is the comic relief we sometimes need. Mr. Gilderoy did more than releasing crazy pixies in a classroom full of students – he actually made us laugh out of our minds.

Start Shopping

Shout out to: squishyshmu for the million dollar attitude

I think we can all agree Hufflepuffs are one of the greatest people on this planet. There are some truly great Hufflepuffs out there, and lots of Harry Potter costume ideas suited for Hufflepuffs. Have you read the Harry the Hufflepuff fanfic story? That one would keep you entertained for a while!

13. Cedric Diggory

Start Shopping

Always Tonks, never Nymphadora, the Metamorphmagus is great as a costume inspiration, since you can play around with her features and hair color. And what better way to celebrate her bravery than dressing up as her?

Start Shopping

Shout out to: AlyCat Cosplay for making our book Tonks dreams come true

Ingenious Harry Potter Costume Ideas 

For people who don’t feel like dressing up that much or for people who want to go all out.

15. The Sorting Hat

I’m not talking a full on Sorting Hat costume, but literally just a hat to wear on your God-given head. What is more low maintenance than that? On the other hand, you can have a blast at any Comic Con event going up to random people and trying to sort them into Hogwarts houses.

Start Shopping

Shout out to: Bianca for being a wise Ravenclaw anxious to be sorted into her house

16. Death Eater

Depending on how you want to play this, you can just buy a pretty cool looking Death Eater mask and say your name is Mark, an underappreciated Death Eater Voldemort never paid that much attention to. On the other hand, you can go full creep with a well-thought Death Eater costume and make a sensation at any cosplay-based event anywhere in the world!

Start Shopping

Shout out to: Michael Burson for pulling off evil like a pro

17. Dobby

Again, the internet is filled with Dobby masks, from some pretty realistic ones to ones that are truly terrifying. Pick your poison! And remember, as Dobby, you are a free elf and a hero of your kind, so don't hold back!

Start Shopping

Shout out to: Klaudia “Karczak” Barczak for not settling for a Dobby mask

18. Professor McGonagall

If you don't want to go for the full Minerva McGonagall costume, you can just buy a Professor McGonagall hat online and be done with it.

It will be impossible for you to be as sarcastic, snarky, and wonderful as her, but you can always try.

Start Shopping

Shout out to: Zwillingsnadel for actually making my jaw drop

19. Dementor

A Dementor costume is pretty easy to find, but you can also fashion your own if you're into DIY. If you want to know more about making DIY cosplay costumes, check out our guide on the best anime cosplay ideas we shared not so long ago!

Start Shopping

Shout out to: mylcreates for the amazing make-up

20. Pets

Harry Potter pets are some of the most beloved animals in the fantasy world.

From Hedwig, the cute, self-sacrificing owl to Crookshanks, the grumpy but lovable cat, or even Scabbers, the rat turned traitor, you can just strap some feathers or cat ears on and have a (semi) complete look.

Shout out to: Maracuja Cosplay for delivering that letter to Harry

Harry Potter Costumes for Creative Geniuses

If you really want to put together a fabulous Harry Potter costume that will Avada Kedavra everyone around you, check out the rest of my ideas below. They are not hard to put together if you buy some of the pieces online, but keep in mind that the best cosplay – and the most important part of this artistic manifestation – is to make the costume yourself from scratch!

21. Professor Trelawney

Professor Trelawney is so eccentric that she needed to be included in this category. You will also have to gather quite a few items in order to cosplay her, from her iconic Professor Trelawney glasses to her long skirt, knitted layers, and head scarf. Don't forget to make the movie version voice and walk around a crystal ball for the full effect. It works with a cup of tea now that I think of it. As long as you say The Grim every few words, you should be fine!

Start Shopping

Shout out to: Joshi Lenferink for going for real tea

22. Quidditch Player

Is your boyfriend a Seeker, Chaser, Beater, or is he a Keeper? *wink *. Lame jokes aside, regardless of your gender, you can impress with a really well thought out Quidditch player costume. You can even go out of budget and get a broom as well, in case you don't have one already.

Start Shopping

Shout out to: Kenzie Cosplays for her spot-on badass Ginny cosplay

23. The Golden Snitch

Speaking of Quidditch, you could also buy gold everything and declare that you only open at the close. A gold sequined dress, sparkly makeup, and some gold wings and you’ll be worth 150 points.

Start Shopping

Shout out to: Sylvia Morales for those magnificent wings

24. Patronus

The cool thing about dressing up as a Patronus is that you can get really creative since a Patronus can be a variety of creatures. Either go for the Patronus you’ve been assigned on Pottermore or for the one you find most stylish. Or you can try finding your worst fear of them all, process it, and make your own Patronus charm against it – as long as it is blue and glowing :))

Start Shopping

Shout out to: BlueCh3rry for a truly magical look

25. Basilisk

Out of all of the amazing Harry Potter costume ideas I would like to try, a Basilisk is very appealing to me, being the snake that I am.

You can play with clothes, prints, hairstyles, contacts, and makeup to create your own interpretation of a Basilisk. Or do you think Nagini is easier? Hmm… have to think about that…

Start Shopping

Shout out to: sophie for a truly unique spin

Finite Incantatem

Now that you’re free from the spell cast by these magical costumes, all there’s left for me to do is wish you happy costume hunting.

I would love to see your Harry Potter costumes on Instagram, be they for Halloween, cosplay, or when you’re visiting the Harry Potter Warner Bros Studio tour, where people love to dress up as their favorite characters. Just use the hashtag #geekftwcostumes.
