I bought this for my 3 year old grandson. He is average size and height, it was a little large, but it will last for a while and I expect he will sleep in it in the winter. He lives in Spain so a bit warm to play in this time of the year. I expect it will last for several years. He loves it!

Got these costumes for my sons who are dinosaur mad the quality is brilliant the detail in the material is excellent I wasn’t expecting them to be so nice great quality for the value they look much more expensive than they were 2 happy boys here

Amazing quality. Washed well on 30degree wash. All-in-one so the tail is attached unlike other dino costumes, you will not lose tail with this one. Highly recommend. My little boy loves it.

Bought this for our four year old nephew for Christmas. It is now April and he has barely removed it. I assume his parents occasionally manage to disrobe him for long enough for his customary weekly bath but apart from those rare events he is wedded to living, eating and sleeping as a dinosaur. We now have the onerous task of finding something to buy him for his birthday that is equally as popular. Tsk.

Got this for my kids and they love it. Honestly im impressed with the level of detail on this for the price. Its brilliant and comfortable for the kids when they wear it. Which is most days as they love playing dinosaurs. Originally got as halloween outfits but unlike most they will get alot of use out of this one. Would recommend for anyone that has dino obsessed kids

Wonderful costumes! Great quality and soft material. My boys love dressing up in these and my 3 year old can put his on easily by himself. Really sweet costumes.
