T In The Park 2009 will take place at Balado, Kinross-shire from 10-12 July.
Festival-goers are being encouraged to dress up on the Friday (10 July) of the event, with prizes given out to those with the best costumes.
The festival will also include a fairground, market stalls, bars and eateries including the Healthy T area, which allows revellers to eat healthily whilst away for the weekend.
T also promotes green initiatives and it became the largest carbon-neutral festival in the world last year.
