    • Good fit!
Size: Large Color: White, Black
I ordered the Morphman Slenderman costume for my slim 12-year-old, and it fits absolutely perfectly! The material is stretchy, durable, and looks just like the character — sleek, spooky, and super fun. My child loved how comfortable it was to wear and move around in. The only small downside is that the mask is a little difficult to see through, especially at night, but it wasn’t a big issue. Overall, the costume exceeded my expectations — great quality, perfect fit, and a total hit! Highly recommend for any Slenderman fan! ... show more

    • Creepy and perfect
Size: Medium Color: Skull & Bones
Fit well with room to grow. Creepy just as my child wanted! I will say it is on the thinner side. Just plan to size up if you need to put a layer underneath.

    • Morphsuits Slender Man Kids Costume - size large
Size: Large Color: White, Black
Review Image by FlyGirl
My son really wanted to be Slenderman for Halloween. This costume fit him well and looked good. He did have a hard time seeing in the dark with it on and he said it got hot walking around the neighborhood. It's definitely on the small side. I'm glad I ordered the large size. He's 8, but on the short and skinny side. Over all, he loved it and it was a great halloween costume. ... show more

My son loves this costume! He has so much fun running around the house in it and will wear it for Halloween also. He wears a boys 7 and is slightly on the smaller side. I bought the medium and it's perfect with extra room for growth. The material is sheer, but thick enough to not be see through. I'll also be able to put some thin pants and a shirt under on Halloween since it will be chilly. Only issue would be that vision is a bit obstructed. He can see a little, but I wouldn't send him out alone in it. Other than that I'm really happy with the purchase ... show more

    • headache on halloween
Size: Medium Color: Black
I bought this costume for my 6 year old. It fit well its very spandex like material so if you have a larger child (mine is very slender) this would be a hard fit as it seems to be made for someone very slender. It was what he wanted to be so i purchased it but in retrospect I would not have. It is a one piece costume so if your child needs his hands you have to unzip half the costume (make sure they have a shirt underneath) and tie the arms at the waist so they can function. The head piece it was hard for him to see at time also be prepared for drool, snot and boogers with the way the mask fits. He ended up with stains on it and finger tips. Little ones running around playing. Overall everyone seeing him in costume loved it especially the kids who were running from Slenderman and he was eating it up. But as a mom trying to getting them in and out of it to pee, and to eat, or if they are hot it was a headache. Also the fingers in the hand part of the costume are very slender so if it is taken off inside out you have to get tweezers to turn the fingertips the right way again. Very difficult to work with on halloween. I would not purchase another costume like this. Overall a 3 in my opinion just know what youre getting yourself into. ... show more
