For the Rock Out With Your Socks Out tour, everyone from the tumblr part of the 5sos family should wear a colored ribbon or wristband. On it write your username so when you see someone with the same color bracelate you can follow each other on tumblr. So basically Instant Friends!
Here are the colors for each leg/region of the tour:
North America Red
Here is what to write on your bracelet.
