Bestival was well known for its fancy dress themed days (usually the Saturday of the festival). In 2005, an attempt was made to set the
Guinness World Record for most people in
fancy dress at any one event. By 2010 this was achieved, when 55,000 festival goers set a new Guinness World Record. The festival was also heavily involved in supporting social and environmental causes. Rob da Bank and Bestival supported several Isle of Wight-based charities and youth organisations; for example Rob da Bank's Music Club, Isle of Wight Toy Appeal, Isle of Wight Youth Trust, St Catherines School and Barter For Bestival. On site at the festival, Bestival supported Oxfam, RSPB, Amnesty International, Water Aid and the Legacy Project. Bestival actively reduced its
carbon emissions and impact on the environment; for example schemes such as Bike to Bestival, Swim to Bestival, LiftShare, exchanging recycling at the campsites for cups of tea, recycling and waste management, commissioning Environmental Impact Assessments, monitoring power usage and limiting water usage with push button taps. Bestival was a founding member of the
Greener Festival Alliance. Bestival was often described as a "boutique festival" due to its non-corporate feel. It was also known for piloting odd and innovative ideas, including an inflatable church where people can get married. Other features included the "Breastival", a quiet
Yurt designated for mothers and their breast-feeding children. The local Women's Institute had also been involved by providing refreshments for a minimal price. ==Performance venues==
