Cat in the Hat Costume Kids Girls – Thing 1 & Thing 2 Tutu Set, Book Week 2026

Description

This Cat in the Hat costume turns one of the most recognisable picture books in the world into a ready-to-wear Book Week 2026 outfit, complete with the red and white stripes every teacher will spot instantly.

The range covers the Thing 1 and Thing 2 characters from Dr Seuss's classic, built around a bright red top and a matching tutu. Depending on the package you choose, you can add a blue character headband, striped arm warmers, striped stockings and a tail. Sizes run through ages 5 to 14 plus a One Size option, and because the pieces are sold as coordinated bundles you can dress one child, a pair of siblings as Thing 1 and Thing 2, or a whole friendship group in the same theme.

Size Guide

This costume is sold in child age bands rather than centimetre measurements, and the tutu and top are cut with stretch and generous ease so they fit across a range of builds within each band. Use your child's usual age-based clothing size as the starting point, and read the notes column for how each option tends to sit.

Sizing tip: if your child sits between two age bands, or you want the top to layer over a long-sleeve shirt on a cool August morning, choose the larger option. The elasticated tutu waist takes up the slack, and a slightly roomy top is far more comfortable across a full school day than one that rides up.

Why Parents Choose This Cat in the Hat Costume

• An unmistakable book character - Dr Seuss's story is on almost every Australian school library shelf, so this outfit needs no explaining at the Book Week parade.
• Built for pairs and groups - Thing 1 and Thing 2 tops are sold separately, which makes matching siblings, twins or friendship groups straightforward.
• Buy only what you need - take the headband alone, a single top, or the complete bundle, so you are not paying for pieces you already own.
• Comfortable for a full day - soft polyester and an elastic tutu waist mean your child can run, sit and play without adjusting the costume every ten minutes.
• Wears well past Book Week - the same set carries through to Halloween, birthday parties, carnivals and everyday dress-up at home.

Fabric & Care

The tops and accessories are made from a soft, lightweight polyester, with a layered tulle-style tutu that holds its shape without needing a separate petticoat. Polyester suits an Australian August well: it is breathable enough for a warm classroom, shrugs off creasing in a school bag, and is ready to wear straight out of the packaging without ironing.

Cold hand wash separately, do not bleach, and hang to dry in the shade rather than using a dryer, as heat can flatten the tutu netting. Reshape the tulle layers by hand while damp and they will sit correctly once dry. Please allow 1-3 cm variance in stated measurements, as each piece is cut and sewn individually.

Book Week and Party Styling Ideas

The Cat in the Hat was published by Dr Seuss in 1957 and remains one of the best-known early readers in the English language, which makes it about as safe a Book Week choice as exists - the brief is to dress as a character from a book, and this one is a book character in the purest sense. Bring a copy of the story along on the day and the connection is made for you before your child says a word.

For styling, lean into the stripes. Red and white striped socks or the included stockings extend the theme down to the shoes, a wild blue wig or the character headband finishes the head, and a tall red and white striped hat brings in the Cat himself if you want a third character in a group. Two children as Thing 1 and Thing 2 photograph beautifully together, and a parent or teacher in the Cat's hat and bow tie completes the scene for a class photo.

Frequently Asked Questions

Do Thing 1 and Thing 2 come together?
No - each numbered top is a separate option, which lets you buy the exact pair you need. For siblings, order one of each in the appropriate sizes.

What is included in the full bundle?
The complete dress-up bundle includes the top, tutu, headband, arm warmers, striped stockings and tail. Smaller packages include fewer of these pieces, so check the option you select before ordering.

Is the tutu adjustable?
The tutu has an elasticated waist that stretches across a range of sizes within each age band, which is why we suggest sizing up rather than down if you are between options.

Can boys wear this costume?
Yes. The Thing 1 and Thing 2 tops and headbands are worn by boys and girls alike; many families pair a top with plain shorts or trousers instead of the tutu.

Will it arrive in time for Book Week?
We dispatch quickly from Sydney and most Australian metro orders arrive within a few business days. Order as early as you can in the run-up to Book Week, as August is our busiest period and courier networks slow under the volume.
