From PDX Anon

As documented in this Enturbulation thread (no longer available), David Miscavige has just declared that Anonymous is actually the Fourth or Fifth Invasion Fleet of the Marcab Confederacy, whose uniform is a black suit and a black fedora hat. So if you are stuck for what to wear, the Invasion Fleet uniform will do just fine.

Masks

The Guy Fawkes mask from the comic and film V for Vendetta was chosen for our efforts, both to hide our identities from the Church of Scientology, and because of the symbolism attached to it. In both the book and the movie, the populace takes up Guy Fawkes masks and rebels against the totalitarian government. In the book, Evey takes up V's mask after his death to make the public appearance he'd promised, even though his death has already been broadcast all over England. Because the identity of the person behind the mask is unknown, anyone can become V. It's analagous to Anonymous, in that anyone can take up the name and be Anonymous.

Masks and/or scarves ARE recommended for four good reasons:

1. Anonymous is Legion: no one is more important than the whole and no one's ideas are more important than when we speak in one voice. Your individual identity is insignificant compared to Anonymous's identity.
2. For your safety: you may scoff at stories of OSA harassment, but this is VERY real. They WILL try to find out who you are, and they WILL try to ruin your life. It's as simple as that. Whether you are an instigator or just a voice in the crowd, they will want to find out who you are. They are having difficulties with Anonymous so they will try to look for a weak link. Research what Tory Christman or Paulette Cooper went through. Fair Game is not fun.
3. As a publicity stunt: it's fun, it's interesting, and it makes us different from other protesters. We need that.
4. If you listen to old school Scientology critics they will all tell you one thing. Tory Christman, Mark Bunker, Molly Bloom have all said "Anonymity is your greatest weapon": we are like nothing they have tried to combat before. They have no clue how to fight a faceless, identity-less body of people. We have them confused and, yes, scared, so let's not lose that by becoming a protest group like any other. They know how to deal with those.

Choice of mask is left up to the individual. However, keep in mind that the 'V' mask has become somewhat iconic to Anonymous and that uniform 'V' masks look good for the media as well as passersby.

If you can't do masks, then at least wear a thick scarf and sunglasses. Some people have mentioned that they have purchased extra masks. Please go to Guy Fawkes mask for more info.
