A wave of naked cyclists biked through the streets of Brighton on Sunday – but it was for a good cause.
More than 550 cyclists ditched their clothes to take part in the 13th annual World Naked Bike Ride on Sunday.
Every year since 2006, Brighton's bravest have taken part in the 'protestival' to demonstrate the vulnerability of cyclists on the road and protest car culture.
Some sported glitter boobs, body paint and creative costumes while others went fully nude for the ride.
They made their way through Brighton town centre, along the seafront to Hove before heading back to Brighton naturist reach for a picnic and swim in the sea.
Since 2007, Sussex Police have permitted full nudity at the event following negotiations.
The Brighton event is one of a number happening in the UK and around the world at the same time, including in nearby Portsmouth.
