How to Style the Romi Halloween Costume

The pink wig is what people clock first, since her hair color is treated as odd even inside her own family in the show. If the wig is too short or too flat, the costume reads as a generic school uniform instead of Romi specifically. The bow tie color matters less than people think, pink and blue both appear on the show across different seasons, so pick either without worrying you got it wrong. At a loud party where nobody watches the show, this can slide into “anime school kid” if the plush is left in a bag instead of carried around all night.

Romi works at her cousin’s bakery and still finds time to secretly turn into a princess to fight problems in Harmony Town, which is a lot of double life to manage before dinner. She does not announce any of this. She just keeps switching between counter work and saving the day, which is the actual joke of the character if you know the show.

Carry the Heartsping plush, don’t just display it

A plush sitting in a bag does nothing for the costume. Hold it, clip it to a bag strap, or tuck it in an arm the way Romi does with her Teenieping on the show. This is the detail that actually gets people who watch the show to say her name instead of guessing “some school character.”

Buy the wig a size up if you have thick hair

Cosplay wigs with adjustable straps still run tight over thick or long natural hair, and a wig cap only helps so much. If your hair is already long, consider braiding it flat first so the wig sits properly instead of tilting back by the second hour.

Romi Group Halloween Costume Ideas

Couples Idea

Romi & Shasha

Might work, but this only lands with people who actually watch Catch! Teenieping, since Shasha has no wide name recognition outside the show. Inside the fandom the pairing is instantly clear. Outside it, expect to explain who Shasha is more than once.

Duo Idea

Romi & Heartsping

Excellent duo if one person is willing to be a plush stand-in rather than a full separate character. Heartsping is Romi’s own Teenieping and the two are rarely apart on the show, so this reads correctly to anyone who has seen even one episode.

Romi Heartsping

Group Idea: Catch! Teenieping Cast

Romi, Shasha, Heartsping, Angeltping, Bowtping

Might work, but none of these characters have a dedicated guide here yet, so everyone past Romi is a build-from-scratch costume. This only works for a group that already knows the show well enough to piece the looks together without a reference page.

Romi Shasha Heartsping Angeltping Bowtping

Group Idea: Colorful Young Fantasy Heroines

Romi, Dora the Explorer, Star Butterfly, Marinette, Luz Noceda, Abby Hatcher

Strong group for a crowd with kids or families, since every character here comes from a different show but the “young girl with a secret power or double life” theme holds the group together without anyone needing to explain the connection.

Romi Halloween Costume DIY Tips

Building the Look

Most of this costume is a school uniform, so a lot of it is either already in your closet or easy to thrift. The wig and the plush are the two items worth buying new.

Uniform pieces: check thrift stores first, plaid skirts and white blouses show up constantly.
Wig: buy this one. Thin, short pink wigs do not read as her hair.
Bow tie: pink or blue, either is accurate. Don’t overthink it.
Socks: any striped knee-high works, skip buying a specific brand.
Heartsping plush: buy this. It is the single item that makes people say her name instead of guessing.
Shoes: plain low heels or flats you already own are fine.

Playing Romi at the Party

Romi hides that she is secretly a princess and spends her free time transforming to deal with problems most people never see. She treats this like a normal errand, not a big reveal.

If someone asks about the plush, say it is your “personal Teenieping” and leave it at that. People who know the show will laugh, people who don’t will just think it’s cute.
She works a normal bakery job on top of the secret princess stuff, so playing tired but polite fits the character better than playing regal.
Skip trying to explain the transformation forms unless someone actually asks. It’s a lot of lore for a hallway conversation.

Romi Halloween Costume: FAQ

How do I dress like Romi for Halloween 2026?

The long pink wig and a Heartsping plush are what carry the costume. Build the base with the pink skirt, white blouse, bow tie, and knee-high socks, or wear the full pink school uniform set instead.

Is the Romi costume still a good choice for Halloween 2026?

Catch! Teenieping is still an active, ongoing kids’ show in South Korea, now on its sixth season, so it stays current for young fans. Recognition outside that specific audience is limited, this one is really built for kids who actually watch the series.

What are Romi’s most famous quotes?

She does not have a big signature catchphrase the way some magical girl leads do. Her most quoted line comes from recognizing a Teenieping’s handiwork: ‘I knew it was a Teenieping.’

What is Catch! Teenieping about?

Romi is a princess from the Emotions Kingdom who secretly lives on Earth catching escaped Teeniepings, small emotion-based creatures, while going to school and working at her cousin’s bakery.

When did Catch! Teenieping first air?

March 19, 2020, on KBS2 in South Korea, produced by SAMG Entertainment. The first season ran 52 episodes.

Why does Romi have pink hair?

It is not explained in the show. It is even noted as unusual within her own family, since the rest of them do not share her hair color.

Do I need the Heartsping plush?

Not strictly, but it helps a lot. Heartsping is Romi’s constant companion in the show, and carrying the plush is what separates this from a generic pink school outfit.
