How to put it together

1
Put on the light grey base layer or the Mewtwo kigurumi onesie.
2
Attach the thick purple tail to the lower back of the outfit, securing it with safety pins or a belt underneath the fabric.
3
If using a separate headpiece, secure the headband with the blunt grey horns onto your head, pulling your hair back.
4
Put on the light grey three-fingered gloves, ensuring they fit snugly over your wrists.
5
Step into the matching light grey shoes or pull the fabric boot covers over your footwear.
6
Adjust the hood or headpiece so the embroidered facial features or horns sit symmetrically.

Makeup & hair

Keep hair completely hidden under the hood or a bald cap. If your face is visible, apply pale purple or grey face paint with sharp, dark purple eyeliner to mimic Mewtwo's intense, serious eyes.

Mewtwo for couples, groups, kids & more

couples: Pair up with Mew for a legendary genetic duo, or a Pokémon Trainer holding a Master Ball.
group: Form a legendary trio with Mew and Armored Mewtwo, or join a group of classic Generation I Pokémon.
kids: A fleece Mewtwo kigurumi is a warm, comfortable, and easy-to-wear option for trick-or-treating.
Plus size: An oversized kigurumi onesie offers a highly comfortable, loose, and inclusive fit for all body types.

Tips

Use a bendable wire inside the tail so you can curve it upward and keep it from dragging on the ground.
If wearing a full kigurumi indoors, wear lightweight clothing underneath as fleece can get very warm.
For photos, strike a powerful psychic pose by holding one hand forward with fingers spread and looking directly at the camera.
