About 15,000 women have spent the night walking through central London wearing decorative bras on a "moonwalk" to raise money for breast cancer research.
The women, and some men, took part in the 11th Playtex Moonwalk, which began at midnight on Saturday in London's Hyde Park, where it also ended.
Eight MPs participated in the 26-mile (41.8km) walk including Patricia Hewitt MP and Margaret Hodge MP.
About £6m is expected to be raised from the walk, £1m more than last year.
The theme of the night was Bollywood meets Rock.
Nina Barough, founder of Walk The Walk, the health charity behind the Playtex Moonwalk, said: "In the past 10 years we have been able to make an important contribution to the lives of people with breast cancer and have encouraged many to lead healthier lifestyles as a form of preventive health."
The route of the "moonwalk" took in the sights of the Millennium, Bridge, Tower Bridge and the London Eye.
The first "moonwalk" began with just 25 participants.
