Stella McCartney may be the queen of eco-friendly fashion, but she’s also all about giving back to disadvantaged youth too.

On what marked the day after the anniversary of the fashion designer’s mom’s death, she kept her head high as she teamed up with H.E.A.R.T. (Helping Ease Abuse Related Trauma) for the foundation’s 14th annual H.E.A.R.T. brunch for the sixth year in a row.

The event, which was held at a private estate in Brentwood, Calif., Tuesday, helped raise money and awareness for the Violence Intervention Program—the largest child abuse clinic in the country. The clinic cares for more than 18,000 victims of abuse, neglect, and sexual assault each year.

“I think that since it’s been the only one of its kind in this state ... it really does blow my mind,” McCartney told InStyle about the clinic. “Every time I am reminded of that, I realize it’s important. If it’s the only place that can cherish, and honor, and love, and support people in need, of all ages, then I don’t understand why I wouldn’t be here supporting it every year. It’s something that we can create—an event where women and men can come and enjoy the process of giving, and also at the same time, they’re receiving. It’s a win-win situation.”

McCartney, who rocked a black fringe jacket, paired with an off-white blouse and khaki-colored pants to the event, brought her daughters Bailey, 10, and Reiley, 6, with her, just a day after she took them to the clinic with her in Los Angeles.

“I was so proud to have them there,” she told the audience, which included Lena Dunham, during a pre-brunch speech. “I was a bit scared going I have to admit. On the way in with my girls, I was saying, ‘this isn’t a lesson feeling guilty. I’m not taking you here to make you feel like you’ve done something wrong for being born into such privileged life. What this is really designed to do is to let us know we can do something. We are privileged, and we are so blessed, and to take that and to try and do something good with it is really allowed, it’s actually allowed.’”

A uniquely curated Stella McCartney pop-up shop was also set up, with guests sifting through racks of clothes and tables of handbags, and buying their faves to help raise money for the nonprofit organization. Some of the ladies in attendance were also styled by Stella and bought the items she selected for them.

In addition to a photo booth, there was also a "Stella’s Cotton Candy" stand on hand. Stella’s two daughters made sure to grab some with one of McCartney’s friends before walking back over to their mom.

As the event wrapped up, guests headed out with bags of their McCartney finds and heart shaped cookies that read “heart” and “love.”
