A lot of Brits are wearing safety pins on their clothes this week, and it's not just a new fashion trend.
Following last week's vote for the U.K. to leave the European Union, racism against immigrants has increased, with many being told to go back to their countries of origin. The Facebook page Post Ref Racism has been set up to document examples of such abuse following the referendum.
Another social media movement is encouraging Brits to wear safety pins to let immigrants know they're safe with them.
"It's simple because you don't have to go out and buy it, there's no language or political slogans involved," she said. "It's just a little signal that shows people facing hate crimes that they're not alone and their right to be in the U.K. is supported."
Allison added that she often has to remind people that she is an immigrant herself. "You know, I'm white and speak English as a first language so I get a pass," she said. "They say 'oh, you don't count, you're not the kind of person we're talking about.'"
The movement is similar to the "I'll Ride With You" campaign, which sought to fight Islamophobia following the 2014 Sydney hostage crisis.
Since the idea was proposed, people have been sharing photos of their pins and messages of hope on social media using the hashtag #safetypin.
