    My 3 year old nephew went nuts. Has since spent the last 6 months since his birthday living life as a dinosaur and perfecting snarling noises. Size was fairly baggy so he probably can enjoy another 3-4 years living as a dinosaur.

    I bought this as a Christmas present for my 5-year-old dinosaur obsessed nephew. He was absolutely thrilled with it spent the next couple of days running around roaring and “scaring” us all. I’m delighted by it too. The quality is outstanding both in terms of the look and the robustness of the costume. I wouldn’t hesitate to recommend it to anyone who has a young dinosaur fanatic in their family. It’s not cheap but it is good value for the price so you do get what you’ve paid for. 5/5

    My 3.5 yo loves dinosaurs and this costume is perfect! The tail swings when he turns around – so much fun! Size wise, my son is quite tall for his age but the suit is nice and roomy, so plenty of space to grow into.

  4. Diane

    My nephew ABSOLUTELY loved this suit……and even went to Bluewater Shopping Centre in it!!! There wasn’t any excess packaging to dispose of. The suit itself exuded quality, the material was plush, soft and vibrant in colour, the tail, claws and spines were well stuffed, realistic and effective, the zip was excellent quality and very functional whilst still being user friendly for little fingers, and the headpiece was easy to put up and down and well fitted. The suit looks like it should have cost more than it did. The sizing was true, whereas so many times in the past I have bought dress up clothes that have been so far from the chosen size as to be a joke, so this was a lovely surprise.

    Delivery on time, nice costume, four year old loves it, fits spot on

  6. Mazie

    This was fantastic and my daughter loved it. She was a stegosaurus for her school assembly. Sizing is great, probably slightly on the big side which is great as it means she’ll get her wear out of it.

  7. Ian

    Good quality costume, not very large fitting 5.5 Yr old has room but not too much he is tall for his age. Great quality spiked and plates on back, good head detail. Quiet warm when on. Good detail on hands and feet claws

  8. Princess

    Super quality and looks so good. My son adores it!

  9. mrs s

    Great quality and value for money. My Dino mad toddler loved this for halloween, running around roaring at everyone

  10. mrs k

    Perfect for a dionsaur mad three year old. He’ll grow into it but for the moment it’s deliciously baggy, so he looks like a late-Jurassic Norah Batty. But most important is the squishy head bit. It’s cuddlable so “Steggo” goes to bed with him every night.

  11. Wil

    Best looking dino at his school! Wore and washed well.

  12. Aidan W.

    Bought this for my 4 year old nephew as he’s mad for dinosaurs, he absolutely loved it. It’s well made and good comfortable material. My 2 other nephew who are 3 now want one for there birthday.

  13. Bella
