The effort is noted and supported, it's great that others are going to do the same - it doesn't matter if it's just a cool t-shirt or going all out, it's the fact that you're doing something and I think it's awesome.
I'm thinking of going to the party as Rain from the Resident Evil film so it should be a laugh, if you guys are round come say hi, or point, or laugh - but it would be great to meet you both
