The motto for all British festivals should be: "Be Prepared". While finding fun outfit options is great, the changeable weather can turn any event from fab to drab. Don't get caught out and ensure you pack some wellies. Few shoes are more famous for festivals than the Hunter Women's Original Tall Wellington Boots (£115), and for good reason. Take inspiration from festival queen Kate Moss and pair with any outfit if you think the clouds are looking a little grey.
