Kids Costumes in Nairobi: Book Week, Career Day & Halloween Guide
When a school announces Book Week, Career Day, a themed event or Halloween, parents often have only a few days to find something that looks good, fits properly and will actually survive a full school day.
This Kenya-focused guide makes the choice easier: start with the event, use your child’s height rather than age alone, and—where possible—pair the costume with the actual story or character book so your child knows who they are dressing as.

Book Week: choose the book first, then the costume
For Book Week, the easiest rule is simple: choose a character your child actually recognises. It gives them something to talk about in class and makes the costume feel connected to the reading activity rather than just dress-up.
Dog Man
If your child loves Dav Pilkey, this is one of the easiest pairings. Start with the Dog Man & Cat Kid books or browse the full Dog Man & Dav Pilkey collection, then pair them with the Dog Man Cape & Mask or the Dog Man Full Costume.
Alice in Wonderland
Pair the Alice in Wonderland Usborne Graphic Illustrated Book with the Alice in Wonderland Costume. There is also an Usborne Graphic Illustrated Series listing that may return to stock.
Little Red Riding Hood & The Gingerbread Man
Both stories are available inside the Fairy Tale Collection Set. You can pair them with the Little Red Riding Hood Costume or Gingerbread Man Costume. The Read It Yourself with Ladybird Collection is another useful reading option when it is restocked.
Roald Dahl: Matilda, Willy Wonka & Oompa Loompa
If your school is doing a Roald Dahl theme, start with the Roald Dahl Collection. Costume options include the Matilda Costume, the Oompa Loompa Costume and the Willy Wonka Costume. Some of these may be temporarily out of stock or in draft while we prepare the next restock.
Harry Potter & Demon Slayer
For older kids and fans of fantasy or manga, KLK also has strong Book Week and cosplay pairings. For Harry Potter, pair the Harry Potter 8-Book Collection or the full-colour Harry Potter set with the Harry Potter Wizard Costume. You can also add a Hogwarts House Keychain or browse our Themed Sticker Packs.
For Demon Slayer, pair the Demon Slayer: Kimetsu no Yaiba Complete Box Set with the Tanjiro Kamado Cosplay Set. Related add-ons include the Anime Crossbody Sling Bag, the Demon Slayer pencil case option and Themed Sticker Packs. You can also browse our Manga, Comics & Graphic Novels collection.

Career Day costumes
Career Day outfits work best when the role is obvious and the costume is comfortable enough for sitting, walking and participating in class.
- Doctor Costume Set — an easy, recognisable Career Day choice.
- Chef Costume Set — useful for Career Day and pretend play; may be temporarily unavailable while awaiting restock.
- Pilot Costume — a strong school-event option when available.
For children who enjoy role play beyond the event, you can also browse all dress-up and costume options and pair them with books from our children’s book collection.
Animal costumes for school themes and performances
Animal costumes are especially useful for younger children, school plays and themed days because they are easy to recognise and often comfortable enough for longer wear.
Current or returning options include the Bear Costume, Fox Costume and Chicken/Rooster Costume.
Superhero and princess costumes
For superhero fans, the Black Panther Costume is a strong option, while younger children may also enjoy the Dog Man Cape & Mask.
For princess and fairytale themes, browse the Elsa Princess Costume, Rapunzel Princess Costume, Alice in Wonderland Costume and Little Red Riding Hood Costume.
Halloween costumes in Kenya
Halloween events are increasingly common in schools, estates, malls and private events in Nairobi. The most practical choice is often something your child can reuse for Book Week, a party or imaginative play later.
Try the Witch Dress Costume, a superhero look, a fairytale character or an animal costume. For the broadest choice, check the Kids Costumes & Dress-Ups collection.
Kids costume size guide
Costume suppliers often label children’s sizes in centimetres. Use the child’s actual height first; age is only a rough guide because children grow at different rates.
| Costume size | Typical age guide |
|---|---|
| 100 cm | About 3–4 years |
| 110 cm | About 4–5 years |
| 120 cm | About 5–6 years |
| 130 cm | About 6–8 years |
| 140 cm | About 8–10 years |
| 150 cm | About 10–12 years |
| 160 cm | About 12–14 years |
This is a general guide only. Always check the individual product listing where measurements are provided. If your child is between sizes, consider the costume style and whether they will wear clothing underneath it.
Comfort matters more than the photo
Before choosing a costume, ask four practical questions: can your child sit comfortably, walk easily, use the bathroom without help, and wear it for several hours? For school events, these details matter much more than an elaborate outfit that looks perfect for five minutes.
