A domino- paint large pieces of cardboard black, then paint white dots.
Duckling- wear yellow sweatsuit and attach a cardboard duck bill to your face with a rubber band.
A dollar- paint cardboard green or wear green and attach this sign- $.
Or a diver- wear a swim mask and flippers.
How about a dork? find some glasses and tape the nosepiece, some too-short checkered trousers, and a white button-down shirt with a pocket protecter.
