A new protest movement sparked by a policeman's ill-judged advice to women students to "avoid dressing like sluts" has taken root in the US and Canada.
Thousands of people - some dressed in jeans, others more provocatively - are taking part in marches, or "SlutWalks".
The aim, say organisers, is to highlight a culture in which the victim rather than rapist or abuser is blamed.
A "SlutWalk" in Toronto last month attracted some 3,000 people. A similar event is due to take place in Boston.
Nearly 2,500 people have signed up via Facebook to attend Saturday's march in Boston.
Boston organiser Siobhan Connors explained: "The event is in protest of a culture that we think is too permissive when it comes to rape and sexual assault."
"It's to bring awareness to the shame and degradation women still face for expressing their sexuality... essentially for behaving in a healthy and sexual way," the 20-year-old told Associated Press.
Police officer Constable Michael Sanguinetti had been giving a talk on health and safety to a group of students at Osgoode Hall Law School in Toronto when he made the now infamous remarks.
"You know, I think we're beating around the bush here," he reportedly told them. "I've been told I'm not supposed to say this - however, women should avoid dressing like sluts in order not to be victimised".
He has since apologised for his remarks and has been disciplined by the Toronto police, but remains on duty.
Meanwhile, his remarks have led to "SlutWalks" not only in Toronto but also in Dallas, Asheville in North Carolina, and in the Canadian capital, Ottawa.
As well as Boston, marches are also planned in Seattle, Chicago, Philadelphia, Reno and Austin.
The SlutWalk Toronto website says the aim of the movement is to "re-appropriate" the world slut.
"Being in charge of our sexual lives should not mean that we are opening ourselves to an expectation of violence, regardless if we participate in sex for pleasure or work," it says.
Everybody, from singles, couples, parents, sisters, brothers, children and friends, are encouraged to join the marches.
The rallies typically end with speakers and workshops on stopping sexual violence and calling on law enforcement agencies not to blame victims after sexual assaults, the Associated Press reports.
