​Halle Berry and Michael Kors team up for Watch Hunger Stop campaign

Thursday, Oct. 16 is World Food Day, but Halle Berry and Michael Kors are rallying all month long in the fight against hunger.

The designer and the actress have teamed up for the Watch Hunger Stop campaign, which combines the powers of fashion and social media to help feed children in hunger-stricken areas around the world.

For each limited-edition watch sold, Michael Kors will donate 100 meals.

It's as easy as taking a “selfless selfie.” Fans can pick up a free T-shirt at any Michael Kors store through the end of the month, and then post a photo of themselves wearing it on Twitter or Instagram with the hashtag #watchhungerstop.

For every post, Michael will donate $25 or 100 meals to the United Nations World Food Programme (WFP).

Additionally, Canadians can pick up a 100 Series timepiece ($355) in gold, silver or rose-gold.

The stainless steel watch feature a detailed map of the world on the grey-blue or turquoise face, while on the back, Michael has engraved his signature along with the message, WATCH HUNGER STOP.

For each watch sold, another 100 children will receive a nutritious meal.

Since launching the campaign in 2013, more than 5 million meals have been donated to needy kids around the world. Last year's campaign was so popular, that models Candice Swanepoel, Lily Alridge and Chrissy Teigen were inspired to get involved.

“After seeing the success of the last Watch Hunger Stop campaign, I knew I had to be a part of it,” Chrissy told InStyle. “Food is obviously such a huge part of my life, and knowing that one in nine people do not have enough to eat is so upsetting."
