Put on the royal blue spandex bodysuit or the matching blue shirt and leggings base.

Pull on the blue balaclava or hood, ensuring the eye holes align correctly if using a full face mask.

Wrap the long pink scarf around your neck, leaving one long tail draped over your shoulder to mimic the tongue scarf.
6

Makeup & hair

Because this costume utilizes a full balaclava or mask, hair should be slicked back or secured under a wig cap. If your face is visible, apply blue face paint around the eyes with sharp white and red accents to mimic Greninja's facial patterns.

Tips

Ensure your footwear is comfortable; blue slip-on shoes or blue socks pulled over sneakers work best.
Make sure the pink scarf is secured with a safety pin so it doesn't unravel while walking.
If using a full morphsuit, carry a small bag for your phone and wallet since the suit won't have pockets.
