Questions & Answers

Q: Is the jumpsuit part of the costume easily removable for bathroom breaks? Are does everything have to be removed each time. Have a all day event.
(1 Answer)
Asked by Brenda | September 20, 2026
Monster Responds...
The jumpsuit zips down the center back, so you will need someone to help you unzip and re-zip it for bathroom breaks rather than stepping out of it on your own. The vest is a separate piece that fastens with hook and loop strips along the right side seam, so that comes off easily without touching the jumpsuit. For a long event, the back zipper is the main thing to plan around.

Q: For the tall options what’s the inseam? Or what height is best?
(1 Answer)
Asked by Svea | October 25, 2025
Monster Responds...
The tall sizes all share a 34 3/4" inseam, which is about two inches longer than the standard sizes at 32 3/4". The torso lengths also run longer in the tall cuts, so if you're finding that standard jumpsuit lengths tend to fall short on you, the tall options are a great fit.

Q: Is the Alien jumpsuit stretchy material?? (1 Answer)
Asked by Mary  | October 18, 2025
Monster Responds...
The jumpsuit is made from 100% polyester jersey knit fabric, and jersey knit does have a natural stretch to it, which makes it comfortable to move around in. Comparing your chest, waist, and hip measurements to our size chart is the best way to make sure you land in the right size.

Q: I am 510 175 waist34 will a large fit me (1 Answer)
Asked by Chris | October 17, 2025
Monster Responds...
At 5'10" with a 34" waist, the Large could work well for you since it has a 35" waist and a 32 3/4" inseam. Keep in mind that costume measurements are the garment's dimensions, so comparing your body measurements to our size chart is the surest way to confirm the right fit.

Q: Will the mask fit over glasses (1 Answer)
Asked by Kiano | October 9, 2025
Monster Responds...
The hood and mask cover the entire head, and the view port is through a mesh-covered character mouth, so glasses can be worn underneath. Keep in mind that the mesh does restrict vision on its own, so wearing glasses inside the mask may limit your sightlines a bit more than usual.

Q: I look to the size chart for the alien adult costume and I don’t know which one to choose. I mesure 5p7, I wear 29 or 30 in pants.
My waist is 32 and my hips is 34
Small or medium doesn’t fit with my measures
Can you help me (1 Answer)
Asked by François | October 5, 2025
Monster Responds...
With a 32" waist and 34" hips, the Medium could work well for you. The Medium measures 31" at the waist and 37.5" at the hips, so your hips fall comfortably within that range, and the waist has just a little ease over your 32". Since costume sizes aren't cut the same as clothing sizes and this is a structured jumpsuit with foam backing, comparing your measurements directly to our size chart is the surest way to feel confident in your choice.

Q: Can I please get the measurements for the kid xenomorph alien costume in XXS? It says Coming Soon on the chart. Thanks (1 Answer)
Asked by Dava | September 30, 2025
Monster Responds...
The XXS measurements are: chest 30", sleeve length 23.5", waist 23", torso length 26.75", inseam 32.75", vest length 17", and hips 29.5". Also worth noting, this is an adult costume rather than a kids' style, so comparing those measurements to your child's body measurements before ordering is the best way to confirm the fit.

Q: I am writing this to clarify what components actually come with this costume. The description states full head mask, but recommended accessories include the deluxe xenomorph mask. Does the mask pictures in the photos come with the costume? (1 Answer)
Asked by Anonymous | September 29, 2025
Monster Responds...
Yes, the full head mask is included with this costume. It's a foam-backed hood that covers the entire head, with a mesh-covered character mouth viewport and fiberfill stuffing inside the top for shape. The deluxe xenomorph mask listed under recommended accessories is a separate upgrade you can add on, but the full head mask that ships with the costume is a solid piece on its own.

Q: Is it possible to add any customization to this costume through this website (at cost, of course). I really like the costume, but I think it's missing a small detail. (1 Answer)
Asked by Morgan | September 22, 2025
Monster Responds...
We don't offer customization services through our site, so the costume ships exactly as designed. That said, this one is built to be tinkered with: the hood has an opening at the back specifically to add more fiberfill stuffing, and the vest attaches with hook and loop fastener strips, making it easy to modify or add to on your own.
