This Toothless costume is a full-body Night Fury kigurumi in soft polar fleece, which makes it one of the easiest and most comfortable Book Week 2026 outfits an older student or teacher can wear all day.
The onesie is a single zip-up piece with the dragon's hood, ears and tail already built in, so there is nothing to assemble or pin on in the morning. It comes in black and white colourways in sizes S through XL, cut unisex to suit teens and adults roughly 150 cm to 185 cm tall. Because it is genuinely warm fleece, it doubles as winter pyjamas and lounge wear long after the parade is over - which is the main reason kigurumi outsell most single-use costumes.

Size Guide
Kigurumi are sized by the wearer's height rather than by chest or waist, because the body of the suit is deliberately loose. Measure standing against a wall without shoes and match your height to the closest band below. The full range spans roughly 150 cm to 185 cm.
Size
Approximate Height
Typically Suits
S
150-160 cm
Teens and shorter adults
M
160-170 cm
The most commonly ordered size
L
170-178 cm
Average to taller adults
XL
178-185 cm
Taller adults, or anyone wanting extra room over clothes
Sizing tip: size up if you are between two heights or plan to wear the onesie over jeans and a jumper. A kigurumi is meant to be baggy, and the extra length in the leg and sleeve is what stops it pulling when you sit down - a snug one is uncomfortable within an hour.
Why Customers Choose This Toothless Costume
One piece, zero fuss - step in, zip up and you are done, with the hood, ears and tail already attached rather than sold separately.
Warm enough for an August parade - polar fleece handles a cold Book Week morning far better than a thin polyester costume.
Wears for years, not one day - the same onesie becomes winter pyjamas, movie-night lounge wear and next year's Halloween outfit.
Unisex sizing - the cut suits men and women alike, so it can be shared between family members of similar height.
Works for adults and teachers - a genuine adult-sized character costume, which is harder to find than a children's one and always well received at a school parade.
Fabric & Care
The onesie is made from soft polar fleece, a brushed synthetic knit chosen for warmth and for the way it holds the dragon's sculpted ears and tail in shape without stiffening or stuffing. It has a light stretch, does not itch against bare skin, and is comfortable enough to sleep in, which is how most kigurumi eventually get used.
Machine wash cold on a gentle cycle or hand wash, do not bleach, and hang to dry in the shade. Avoid a hot dryer and a hot iron, as high heat can flatten and mat the fleece pile. Please allow 1-3 cm variance in the stated measurements, as each suit is cut and sewn individually.
Book Week and Party Styling Ideas
Toothless comes from How to Train Your Dragon, which began life as a children's novel by Cressida Cowell before the films arrived - so the dragon is a book character first, and that satisfies the "come as someone from a book" brief Australian schools set for Book Week. Carrying a copy of the novel on the day makes the literary link explicit for teachers.
For styling, the onesie does almost all the work. Add black or dark trainers, or slippers if the parade is indoors, and keep the hood up so the ears read from a distance. Pairs and groups are effective here: black and white onesies together look deliberate rather than mismatched, and someone in a Viking-style vest and fur trim as the dragon's rider completes the scene without needing another full costume.
Frequently Asked Questions
Does the tail come attached? Yes. The hood, ears and tail are all sewn into the onesie, so there is nothing to attach or pin on before wearing.
Will it be too hot to wear all day? It is genuinely warm polar fleece, which suits an August Book Week morning well. On a warmer day, wear light clothing underneath and unzip partway when indoors.
Is this suitable for children? The sizing starts around 150 cm, so it best fits older children, teens and adults. Younger children will find even the small size long in the leg and sleeve.
Are slippers included? No - the package is one onesie. Slippers and any additional accessories are sold separately.
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 lead-up to Book Week, as August is our busiest period and courier networks slow under the volume.
