Hundreds of men and women flooded downtown D.C. on Saturday, taking part in a women's rights campaign dubbed "SlutWalk."
The goal of the campaign is to spread a message: no woman deserves to be a victim of sexual assault, regardless of her dress or physical appearance.
The movement started in Toronto after a police officer there said women could being raped by not dressing like "sluts."
That comment, made in January, sparked widespread outrage, and "SlutWalk" marches have taken place in cities in Canada and around the United States, including Dallas and Philadelphia.
"Hey ho, ho ho, sexual violence has got to go," marchers chanted as they wound their way from Lafayette Square to the National Mall.
Some stripped down to bras, other carried signs.
"I had to be here," Erin Longbottom from Fredericksburg told News4, "maybe this is not going to change the world, but it might change some people's minds."
