Dinosaur costume

by Rebecca

Brilliant! As soon as it was unboxed our almost 4 year old demanded to wear it straightaway. Exceptional quality, perfect size. Elasticated hood means it stays on perfectly. Our son wore it for halloween at nursery- not quite your typical halloween theme but at least he can wear it all year round which he would gladly do so as he is dinosaur mad. Because the quality is top notch I am positive this will last until our 1 year old is old enough to wear it.Costume has a textured 'crocodile' design which makes it even more authentic. Definitely a costume to purchase!


Very happy with this costume

by Attea Hylko

I would give this costume more stars if i could. It is very well made, incredibly soft, it is made with good quality material and silky soft liners. The size chart is spot on. My son loves it, I'm very pleased!
