Tips

Opt for a half-mask or face paint if you plan to eat or drink at a party, as full latex rat masks can limit visibility and ventilation.
Scuff up the bottom hem of the robe with sandpaper or dirt to give it a weathered, sewer-dwelling look.
Ensure your walking staff is lightweight (like hollow plastic or light wood) so it isn't tiresome to carry around all night.
