"I would recommend buying a size larger than you would typically buy - I purchased the size 2T/4T and the length in the legs fit my almost 3 year old fine, but it was very tight in the torso, pulling down at the neck. He also complained that the dinosaur head "was choking me!", so I ended up pinning the chin flaps for the head piece down to his shoulders. The quality was what I expected, and it was a very cute costume. However, after 2 weeks of wearing it around the house, and 2 Halloween parties, and trick-o-treating, the tale split open."
"The quality of this costume met my expectations, but I would recommend that you purchase the next size up from what you might typically buy....this costume runs small. My son is a skinny typical size 5, and this outfit fit him like a glove...WITHOUT the inflatable belly. Once we tried to shove the belly down into the costume, the pants became major high-waters, and he developed a bit of a wedgie! But he loved the costume...especially the mustache."
