I was surprised with how comfortable my little one found the triceratops outfit, she didn’t complain and wore it all day! It’s well made and has been through the wash a couple of times. Plus she looks adorable as a tiny dinosaur.

Bought this to match my sons costume as part of our Jurassic park themed Halloween costumes. Really good quality on the larger and smaller sizes. However the small size definitely came up small we ended up with a size 12-18mths for our 7 month old leaving enough room to put warm layers under.

My daughter has gotten so many compliments whilst wearing this costume. It’s well made, a great size and super cute.
Amanda –
Omg!! This costume is amazing!!! Sooo worth the money. Good quality and great fit. My grandson looked adorable in it. Would highly recommend.
Rahel –
Perfect costume for Halloween. Our baby looked super cute. We ordered the costume a little bigger so that we could wear a warm jacket underneath.

I got this for my 2yo son who’s dinosaur mad. It was for Halloween dress up. He’s more into trex but I got triceratops just for a change and I’m glad I did. So many people stopped to see him and compliment his costume at the Halloween event. The only triceratops there and he made everyone smile. Worth the money alone for making my son feel like a real dinosaur for a day

Thick material, great for putting over clothes. Only thing I’d say is the hood is really small, and the seam ended up at the top of his neck and was too tight for him to wear it up, then couldn’t really tell he was a dinosaur without the hood up.

This was great for my 18 month old

Purchased for my 2yr old grandson for Xmas. Material and quality felt good and think it will be something that he will love to wear

I bought this costume for my little boy a while ago now to wear for Halloween as he is Dino mad. I was pleasantly surprised by the quality of the item and how well made it is. It was a little on the large side to start with but he’s grown with it and had it a couple of years now and he’s worn it for 2 Halloweens and more recently WBD. It’s such a cute, fun, well made costume and washes well. I would definitely buy another or similar from this site again now that he has outgrown this one.

My toddler is refusing to get out of it and keeps roaring at me when I try. I may be peeling a sleeping child out of it

Bought for my 2.5 y/o and he loves it so much. Really good quality (it had tags from the Natural History Museum), comfortable fit, easy for him to run around in, and easy to take on and off.
