Review: My son loves this. 2nd year and still works - Great blow up costume. Got this for my son when he was 3 it was a little big but stayed on with the draw string and the strap around the back of the neck. A year later still fits him great and still works! Just take extra batteries with you if you go trick or treating with this my son uses it so much it died out last year so I learned that lesson. He loves Dinos so much he wants to wear this again this year. Easy to put on and you can put a long sleeve and pants on with this too keep them warm as well as a jacket on top if needed. ## Features - 【Product Size】Deluxe Version of Inflatable T Rex Dress Costume.

Super easy to put on and inflate, and the design is adorable — my kid got tons of compliments. The fan runs quietly and keeps the costume fully inflated throughout trick-or-treating. It’s lightweight and roomy enough to layer clothes underneath if it’s chilly. Just make sure to bring extra batteries for the blower. Great quality and big fun for Halloween! ## Frequently Bought Together - One Casa Inflatable Dinosaur Costume Riding T Rex Air Blow up Funny Fancy Dress Party Halloween Costume for Kids - One Casa Inflatable Dinosaur Costume Riding Diplodocus T Rex Air Blow up Funny Party Halloween Costumes for Adult - One Casa Inflatable Dinosaur Costume Riding T Rex Air Blow up Funny Fancy Dress Party Halloween Costume for Adult --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/311214409-inflatable-dinosaur-costume-for-kids-blow-up-halloween-t-rex](https://www.desertcart.jp/products/311214409-inflatable-dinosaur-costume-for-kids-blow-up-halloween-t-rex) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-27*
