The 5 Coolest Dinosaur Costumes [Ranked]

If you're starved for costume ideas- you cannot go wrong with a dinosaur costume.

While the most popular is undoubtedly the inflatable T-Rex, there are some plush fabric slip-ons ideal for adult and children as well. The inflatable options are battery-powered by double AA or triple AAA fans.

This one even comes with a roaring sound!


Buyer Feedback

Examining buyer feedback- purchasers say that these goofy costumes hilariously flop around. This weird contrast of terror and hilarity make them cosplay favorites whether you're celebrating Halloween or in a corporate costume competition.

It can be a little difficult putting it on for the first time. You'll need to first insert your head and arms and then wriggle your legs in.

One bit of warning- if you wear the costume in public, you will attract a lot of good (and bad) attention!

Buying Tips

One of the more popular options that we've seen is an officially licensed Jurassic World inflatable type- it comes in three different types of configurations a basic inflatable one, one with sound and a Velociraptor. 

  • One reviewer said that she purchased it as a gag gift for her friends birthday- he fell so in love with it that he started constantly wearing it. Since he loves attracting attention so much, he wears it outside and to different events including ice skating, bowling, skateboarding, which at least shows that it is pretty durable. 
  • On the plus side, the battery life is strong- her friend has worn it for over nine hours at a time without it deflating. It's incredibly popular with kids, and is good if you're in a colder climate because it tends to warm up on the inside.
  • On the downside, though, you will got a lot of negative attention-people will harass you for selfies and photos, while also attracting more negative attention from people that will want to hit, punch and otherwise try to harm the costume.
  • One reviewer assembled a handy list to help you put it on- he recommends that the first thing you should do is lay on the floor with the zipper facing up, insert your legs, then crouch into a ball, before very carefully rolling it over your head. Now that you're inside, the fan is on, you can zip it up and then insert your hands to each of the arm holes.
  • This buyer says that it does get really hot inside-even after several minutes he will begin to feel it warm up and you will likely break into a sweat. This means that if you plan on wearing it for several hours at a time, indoors, you may want to take some rest breaks so that you don't overheat.
  • Another reviewer who works at a theme park says that her primary job responsibility is to give customers a gentle flight-this particular style of costume fits the bill. 

In general, it seems that buyers are pretty satisfied with what they get-they do recommend purchasing it in advance, especially if you are planning on wearing it to trick-or-treat or compete in a cosplay event. You'll want to make sure that it fits, that there is nothing defective about the fan or material, that way you'll have time to return it in advance.
