How to put it together

1
Put on the black spandex bodysuit or compression layers as your base.

Secure the segmented tail around your waist, positioning it to drape naturally behind you.
3
Slip on the biomechanical chest piece or vest over the bodysuit, adjusting the straps for a snug fit.
4
Put on your boots or pull the ribbed shoe covers over your footwear.
5
Pull on the clawed gloves, ensuring they overlap with the sleeves of the bodysuit to hide any skin.
6
Carefully put on the elongated Xenomorph mask, adjusting the eye slits for maximum visibility.

Makeup & hair

Tuck all hair into a wig cap or balaclava before putting on the mask. If any skin is visible around the neck or eyes, apply black cream makeup to blend it into the costume.

Tips

Visibility can be very limited in a full latex mask; always have a friend act as a handler to help you navigate crowds.
The full bodysuit and latex mask trap heat quickly, so wear moisture-wicking undergarments and take frequent breaks.
Apply a thin layer of clear gloss or petroleum jelly to the teeth and jaw of the mask for a wet, drooling effect.
