Statue of Liberty costume for camp scavenger hunt

I was a camp counselor at a camp in Germany called Seemoos.  One of their events was that counselors would disguise themselves and "hide" around the city of Friedrichshafen.  There were people who were hard to spot, like a guy dressed as a cleaning lady doing window.  I was easier to spot.  I stood at the edge of the harbor painted green.  (date approximate)
