How to put it together

1
Choose your angle: decide if you are going for a terrible pun, an awkward giant object, or a hilariously bad mashup.
2
Keep the materials intentionally low-budget, using cardboard, markers, or cheap foam to emphasize the bad aesthetic.
3
Add a confusing accessory, like a glamorous feather boa paired with a terrifying monster mask, to mimic cheap mass-market designs.
4
Write any jokes or puns clearly on your outfit so people do not spend all night guessing your confusing concept.
5
Wear comfortable base layers underneath, especially if your bad costume involves stiff cardboard or hot, sweaty foam.

Makeup & hair

Keep it intentionally messy or completely mismatched to your outfit, such as smeared clown makeup paired with a formal business suit.

Tips

Make sure your joke is easy to understand at a glance so you do not have to explain it fifty times.
Avoid offensive or culturally insensitive themes; stick to harmless, absurd, or self-deprecating humor.
Test your mobility and vision, especially if you are wearing a giant foam suit or a cheap plastic mask.
