The 99-Nights Kids Deer Monster Costume transforms your child into one of the creepiest figures from popular horror-inspired games. Designed in a deep brown colour with blood-stained claw marks and graphic deer mask detailing, this cosplay set captures the eerie atmosphere of survival horror perfectly.
This 9–10 years costume is available in two versions (brown and grey). The brown set includes:

Crafted from lightweight polyester, the jumpsuit is comfortable enough for trick-or-treating or role play, while the creepy mask adds instant scare factor. Perfect for kids who want something more terrifying than classic skeletons or vampires.
