As you probably guess, the theme is “Travel”.
You don’t have a real dress code to have, with special colors, flowers in the hairs (if you got hairs of course…). No ! Nothing like that.
The only thing we ask you to have, and to be visible of course, is to have something that represent your country/city/land/region…
For example, you can have a “burger hat” if you come from the USA, or a pin’s with a fish if you come from Atlantis. You see ? 😉
