Women practise a pole dancing move during an International Women's Day event at a women's-only pole dancing fitness studio called Studio Exclusive, in Sydney on March 8. The event raised money for "White Ribbon" Australia, a campaign to stop violence against women. On March 8, activists around the globe celebrate International Women's Day, which dates back to the beginning of the 20th Century and has been observed by the United Nations since 1975. The UN writes that it is an occasion to commemorate achievements in women's rights and to call for further change. Reuters/Jason Reed
