BayCon 2007 Hall Costuming Guidelines
Do keep it PG 13-rated when walking around in the hotel (the No Costume is No Costume Rule).
Do follow the Weapons Policy at all times. Remember, if you kill it, you eat it.
Don't have anything messy in your costume (the No Peanut Butter and Jelly Rule). If it is likely to fall, fly, rub or ooze off your costume onto a chair, wall, floor, or other person, don't wear it.
Don't bring any live animals to the con, even if you think it is an integral part of your costume. Your live iguana familiar is, sadly, not permitted. The hotel will absolutely not allow it.
Do be aware of what you are wearing. If parts of your costume extend beyond your average personal space, be careful and try not to bump, poke, spear, or skewer those around you! Don't expect others to look out for you — you are the one wearing it.
Do keep in mind that this is a relaxed endeavor. Skilled crafts men/women/elves/Klingons as well as creative amateurs are welcome.
Do be kind to mundanes. Yes, they will probably ask the same old questions ("What are you s'posed to be?" etc). But try to think of them as unenlightened souls who need to be educated in the wonderful way of fannish costuming. Educate them when possible, ignore them if you must, just don't freak them out too much!
Look out for the roving Hall Costume Judges who will be awarding Hall Costume Prizes throughout the weekend.
