I'm used to wearing 5-lb costumes. At least this one will have a hoop skirt to hold it up for me XD Though I wouldn't fit into an elevator with other people, and escalators are right out. So I'd put it on and camp out in a visible area for a while, and make sure there aren't any panels I want to go to during that time period. (A visible area so people will stop and take my picture, of course!) I'd also enter into the costume contest.
