Virus Costume
Go microscopic with a green, spiked germ or computer virus costume.

How to put it together
- 1
Put on the black leggings or pants and a matching long-sleeve undershirt.
- 2
Lay your green or red tunic flat on a table to plan your spike placement.
- 3
Attach the large red pom-poms or painted styrofoam balls to the front of the tunic using hot glue or safety pins to create a 3D microscopic look.
- 4
If using pipe cleaners, twist them around the base of the foam balls first to give the spikes some height before securing them to the shirt.
- 5
Slip the decorated tunic over your head, adjusting any stuffing if you want a rounder, more spherical shape.
- 6
Place the matching spike headband on your head to complete the cellular structure.
- 7
Carry a small spray bottle labeled 'Disinfectant' or 'Hand Sanitizer' as a funny, interactive prop.
Makeup & hair
Keep it simple with bright green face paint or green glitter on your cheeks. Alternatively, style your hair in messy spikes using strong-hold hair gel or temporary green hair spray.

Tips
- If you use foam balls, choose lightweight styrofoam so the tunic doesn't sag or pull forward.
- For indoor parties, keep the tunic lightweight and breathable; avoid heavy stuffing if it's warm.
- Add a computer mouse or a 'Loading...' sign if you want to pivot the theme to a 'Computer Virus' instead.
- Ensure your spikes are securely glued or pinned so they don't pop off when you sit down or hug people.
