Dinosaur… rawr 🦖

"I have been looking for the perfect dino onesie, for quite some time, and had always struggled to find one that I really liked… until I came across this adorable option :D I really appreciated the website’s in depth sizing information, and the speed of delivery (with this being purchased for an event) Customer service is great, too! Upon its arrival, it was packaged nicely, and securely, and the onesie itself is so very soft, and easy to put on (which is very important to me, as an autistic and dyspraxic person) The only thing that I think would make it better would be the option to pay via PayPal All this to say - thank you, OppoSuits! I am a very happy customer! :3"

Excellent is an UNDERSTATEMENT

"Everyone adored our costume—the giraffe. It was so unique and looked great. Quality-wise, it was definitely worth every penny we spent."

— Gem P. (5/5)

Ok

"It’s cute and fits well, but one of the flippers started tearing off just 3 days in. Also would be helpful to have Velcro or something to pin up the flippers when not wearing. Kind of dangle and get in the way."

Material macht einen guten

"Material macht einen guten Eindruck. Fühlt sich alles bequem an und passt. Wenn an den Seitentaschen Reißverschluss wäre, wäre top."
