Festival hat
From Guild Wars Wiki
Festival hats are decorative headgear that is typically only obtainable during special events. The Festival Hats are sometimes considered prestige items as they demonstrate the players were around when a certain event has occurred. Festival Hats are customized for the original owner only. As a decorative item these hats will typically have little to no armor rating, but will usually accept runes and sometimes dye.
[edit] Festival hat makers
A festival hat maker can copy a festival hat you have shown to them. After you have shown a hat to a hat maker, it is available to craft for all the characters on your account for a fee of 10 
, and it will be automatically customized for this character. Festival hat makers will only copy hats that are customized for you. This means, although festival hats are tradeable, they cannot be used or copied by characters that are from another account. This means buying festival hats is extremely ill-advised.
[edit] Acquisition
Festival Hats are acquired from certain special events, such as the Dragon Festival, which was recently commemorated on Canthan grounds. Special events often have a specific item or a special reward token created only for the event in question. (Some tokens like Victory Tokens get reused, but others do not.) In order to get the Festival Hat, you usually have to gather a certain amount of these tokens to claim the hat. If you play Guild Wars on a regular basis and read the announcements, you are sure not to miss the events that give out these hats. Note:When obtaining the hat, if your inventory is full, the hat will drop on the floor in the town/outpost until you clear space enough in your inventory, then you can pick it up.
