Questions & Answers

Q: Is this costume unisex? As a 5 foot 4 female that weights 135 pounds should I order a small ? (1 Answer)
Asked by Tamra | September 30, 2026
Monster Responds...
This costume is sized for adults and works great for anyone who wants to rock a brontosaurus look. At 5'4" and 135 pounds, your chest and waist measurements will likely fall well under the Small's 42 3/4" chest and waist, so the Small could work well for you. Comparing your body measurements to our size chart is the surest way to land on the right fit.

Q: Would this brontosaurus costume fit a thin woman, 5'7"? (1 Answer)
Asked by Leslie | October 11, 2025
Monster Responds...
At 5'7", the torso and inseam measurements are the most important to check here. The Small has a 32 3/4" torso and 28 1/2" inseam, and the Medium steps up to 34 1/4" torso and 29 1/2" inseam. For a thin frame, comparing your torso length (measured from where your shoulder meets your neck down to your crotch) against those numbers will tell you which size gives the best length fit, and since the chest and waist on even the Small run quite generously, a thinner build should have plenty of room.

Q: How tall is the costume? Im 6’3” and want to make sure it fits my height (1 Answer)
Asked by Anonymous | September 9, 2025
Monster Responds...
At 6'3", your torso and inseam measurements are the key numbers to check here. The X-Large has a 37 1/4" torso and a 31 1/2" inseam, which are the largest available in this jumpsuit. Measure your torso from where your shoulder meets your neck down to your crotch, and your inseam from crotch to ankle, then compare those to our size chart to find your best fit.
