Designer Stella McCartney has designed a brooch for the White Ribbon for Women campaign to raise funds for the elimination of violence against women.
Explaining why she's got involved, McCartney said: "Statistics show that one in three women around the world are beaten, coerced into sex or otherwise abused in their lifetime."
"This is a horrific fact that has inspired me to bring attention to the awareness campaign to stop violence against women. I cannot stress enough how important it is that people are aware of the facts... and support women to find the courage to break the silence."
A total of 125,000 brooches have been created and will be distributed across more than 800 Kering-owned boutiques including Gucci, Balenciaga and Alexander McQueen in 41 countries, reports femalefirst.co.uk.
The initiative launched on Saturday and will run till November 25 to coincide with the International Day for the Elimination of Violence Against Women.
The project will run alongside a social media campaign using the hashtag #BeHerVoice, building on the success of 2014's efforts which saw Sarah Jessica Parker, Alexa Chung, Bradley Cooper and Cameron Diaz among the famous faces backing the initiative on Twitter and Instagram.
