Product description
The Pink Dino Critter Onesie in big-kid sizes: a thick flannel jumpsuit with the full animal hood, for children 100 to 140 cm tall.

The Pink Dino design
Nobody knows exactly what colour most dinosaurs were, although fossil pigment cells show some feathered ones were reddish-brown. So a pink dinosaur is as plausible as any. For the dino fan who wants their own colour.

Dress-up that gets worn again
A costume that is also comfortable is the one that comes out of the drawer after the party. Thick flannel and a roomy cut make this one a weekend-morning favourite as much as a costume.

Sized by height
Pick the size that matches your child's height: 100 cm through 140 cm. If they are between two, go up — it is a loose, relaxed fit by design.

A dinosaur in her colour
She has wanted a dinosaur costume for ages, but only in pink. This ended a very long search.

She has the science on her side
The listing points out nobody knows what colour most dinosaurs were. She now uses that line on anyone who says pink dinos are not real.

Stood out at the dino party
A sea of green dinosaurs and one pink one. Guess who everyone remembered.

Thick and soft
Heavier flannel than I expected for the price, and soft on the inside too.

Museum guide played along
At the fossil museum the guide told her pink dinosaurs were entirely possible. She glowed for the rest of the day.

Pink and green sisters
Pink for one daughter, green for the other. They stomp through the house as a pair.

Warm Halloween
Cold, damp Halloween and she was warm the whole way round. Lots of people stopped to say they loved the colour.

Fits a tall seven year old
126 cm in the 130, relaxed but not swamped. Glad it goes up past the toddler sizes.

Favourite colour, favourite animal

Gentle stomper
My daughter is shy, and the pink dino lets her be loud for a bit. It is lovely to see.

Sleepover talking point
She wore it for the film at a sleepover. The other girls now all want their own pink dinosaurs.

Frequently asked questions
Which size should I order?
Match the size to your child's height in centimetres — a 115 cm child takes the 120. Between sizes, go up.
How do I wash it?
Machine wash cold, inside out, and let it dry flat or tumble on low.
Can my child sleep in it?
No. It is a costume and loungewear, not sleepwear. It is a loose, hooded plush garment; children should sleep in close-fitting sleepwear with nothing near the face. Take it off before naps and bedtime, and keep an eye on a baby in it so they do not overheat.
