On halloween if a certain element is key to your costume, bring a backup. You'll likely lose one and need a replacement.

For instance - a mustache. you might lose it bobbing for candy apples, motorboating Elvira or kissing Rainbow Bright. Now your costume is without its mustache. And that mustache is needed. Well lucky you - brought an eyebrow pencil with you - and you can simply draw a new mustache in. Now that 1970s cop costume is back in business and you can keep having fun.
