Fans at T In The Park are being invited to arrive wearing a wacky costume as part of the festival's first ever 'Dressing Up Friday'.
A new attraction for 2008, organisers want to turn the Friday (11 July) into the most colourful campsite in the UK.
They are asking campers to come in all kinds of fantastic costumes, whether they be historic, superhero themed or in homage to the festival itself.
They told fans: "Whatever you do, make sure you pull out all the stops! T in the Parkers always do it best so show us what the festival means to you."
Festival goers are also being encouraged as decorate their tents and camping areas, and a photographer will be roaming the campsite. The best costumes and most innovatively dressed up tents will be rewarded with the very first tickets to T In The Park 2009, and the winners put on the website post event.
T In The Park 2008 takes place at Balado, Kinross, Perthshire, from 11-13 July, featuring sets by Rage Against The Machine, The Verve, R.E.M, Kaiser Chiefs, The Chemical Brothers and many more. More info HERE.
Tickets to next year's event will go on sale on the Tuesday after (15 July) at this year's prices.
