Costume and cosplay ideas to heat up your school cultural festival

10 years as a kindergarten teacher / elementary school teacher / junior and senior high school teacher / childminderkepiko
Graduated from Kunitachi College of Music, Faculty of Music (now: Department of Music Culture and Education, Early Childhood Music Education major). In elementary school, my homeroom teacher was Jun Kusaba, a game researcher. After graduating from university, I worked as a kindergarten teacher for 10 years and as an after-school childcare instructor for 7 years, then took a position as a music teacher at an international school in Singapore. In addition to music education, I engaged in activities that introduced Japanese culture, traditional games, and recreational activities, working with many children. Later, through freelance writing, planning, and editing at Shogakukan, I met many delightful adults and experienced the joy of communicating and sharing. Drawing on the perspective cultivated in the field of education and my experience as an editor, I provide practical information with an emphasis on both input and output, mainly in areas related to music and children. My hobbies include instruments, singing, handicrafts, toys, drawing, traditional games, the outdoors, and books. My special skill is spinning-top tricks.

Currently, I mainly handle articles for children, drawing on what I’ve learned about parenting and what I feel and discover through daily interactions with my kids. I hope my work can be of help to you, even in a small way!

At school cultural festivals, there are all kinds of events—exhibitions, food stalls, and even stage performances! Among them, many students probably want to stand out and have fun in free-style outfits, such as stage performances or costume contests.

Since it’s a once-a-year event, you want to make it a memorable day by dressing differently from usual, right? In this article, we’ll introduce recommended ideas for those looking for costumes and outfits for cultural and school festivals.

We’ve picked a wide range, from classic outfits to slightly more elaborate cosplay, so please use it as a reference.

Costume and cosplay ideas to amp up the excitement at school cultural festivals (1–10)

Amate Yuzuriha (Mobile Suit Gundam GQuuuuuuX)

Amate Yuzuriha (Mobile Suit Gundam GQuuuuuuX)

Released in January 2025, the film Mobile Suit Gundam GQuuuuuuX has also begun airing as a TV anime from April.

The movie drew 850,000 viewers in its first 10 days and was a big hit.

Following Mobile Suit Gundam: The Witch from Mercury, which for the first time featured a female pilot as the protagonist, the female lead of Mobile Suit Gundam GQuuuuuuX, Amate Yuzuriha, seems like a cosplay choice that would draw attention.

Amate Yuzuriha is portrayed as a high school girl.

Since her age is close to students who hold school and culture festivals, the cosplay should fit well.

And when it comes to Gundam, don’t forget to carry a Haro with you—that’s an essential touch.

maid outfit

maid outfit

When it comes to cosplay, you just can’t leave out maid outfits! You can easily buy a costume, or if you already have a black dress, you could probably pull it off by just getting a frilly white apron.

Besides the classic black-and-white look, there are lots of variations in colors and styles, so it’s easy to add originality and avoid matching with others.

It might be fun to go all out with accessories—like adding cat ears—for an extra cute touch.

If your class is putting on a maid café, this outfit is absolutely essential.

Japanese doll

@runchan162
Last school festival!! Rocking my natural hair as a Japanese doll ♡ It was seriously so much fun ♡♡ *I wore a kimono we had at home, so please don’t say the obi doesn’t match, and I dressed myself, so please don’t point out anything that’s not correct…#ljk's wonderful memories #06 #07 High school student #jk #ljk #LJK High school girl #Cosplay Cultural Festival

Doesn’t that bob haircut of the wildly popular dance group Avantgardey remind you of traditional Japanese dolls? Combined with how Avantgardey often performs dances to classic Japanese pop songs, it kind of evokes a Japanese vibe.

If you want to create a slightly mysterious atmosphere, I recommend a Japanese doll cosplay.

You can actually find kimono at surprisingly low prices in vintage clothing stores.

A long straight wig makes it even better.

If you paint your face and hands white, you can turn into a Japanese doll that’s almost scary.

Just be careful not to frighten the little kids visiting the school festival!

Costume and cosplay ideas that excite at school cultural festivals (11–20)

Genshin Impact

The person Furina pointed at will be blessed with good luck for the whole year! #Genshin #GenshinImpact #Furina #Mualani #Natlan #GenshinCosplay #芙宁娜

Genshin Impact

If I started writing about what makes Genshin Impact so appealing, the room would probably fill with people saying, “I can explain it better,” or “Only I can truly convey its charm!” Well, one of its draws is the freedom—you can kick back and ignore tasks and the story if you want.

And of course, arguing over which character is best is pointless; there are as many lovable characters as there are players.

If you’re in a class full of gamers, Genshin cosplay might be a must, too.

Personally, my recommendations are the Traveler, Pyro, Valesa, Olorun—no, maybe Xianyun… I can’t pick just one.

Ensemble Stars

Ensemble Stars, which began as a smartphone game, is an idol-training game that has garnered attention for its various media mix expansions.

Because it’s especially popular among women, it’s often used as a theme for cosplay, frequently serving as a basis for cross-dressing into male characters.

Another key point is that the distinctive characters wear a wide range of outfits, so choosing which character in which costume to portray is where your sense of style really shows.

It’s also important to select outfits suited to the occasion—whether you prioritize glamorous designs or ease of movement.

Yor (SPY×FAMILY)

How about a costume inspired by Yor, the mother-role character from the manga SPY×FAMILY serialized on Shonen Jump+ by Tatsuya Endo? Including the hairstyle, the outfit is predominantly black, and the character exudes a gentle aura while also being strongly sexy.

The flared, cape-like skirt at the back and the high-heeled boots are particularly striking.

While the classic choice is her black, spy-like outfit, recreating some of her everyday clothes could offer a different kind of fun as well.

B Komachi (Oshi no Ko)

[Oshi no Ko] B-Komachi “Sign is B” Tried Dancing [GGKD]

B Komachi (Oshi no Ko)

How about dancing to an idol song in a costume inspired by the idol group the new B-Komachi from the 2023 anime “Oshi no Ko”? The outfit introduced here is the school uniform worn by the members of B-Komachi.

If you customize a ready-made uniform, you won’t have to make it from scratch, so it’s an easy option.

It’s also sold on online shops, so you can purchase it when needed.

In addition, B-Komachi has a black outfit that they wear on stage.

If you prefer something other than the uniform, be sure to check that one out too.
