How to put it together
- 1
Put on the green or teal base onesie or hooded sweatshirt.
- 2
Attach the stuffed green tail to the back of your waistband if it is not already built into the outfit.
- 3
Pull up the hood and adjust it so the cartoon eyes and snout sit clearly on top of your head.
- 4
Wrap the blue felt water ripples around your waist or secure them to your shoes to create the illusion of emerging from Loch Ness.
- 5
Put on matching green gloves or socks to complete the seamless, monstrous look.
Makeup & hair
Keep hair tucked neatly inside the hood. For makeup, apply simple green face paint around the eyes or add blue glitter to your cheekbones to mimic sparkling lake water.
