Lauren Conrad heads out for a workout with her dog Chloe and a friend on Saturday afternoon (August 11) in Brentwood, Calif.

The 26-year-old designer recently unveiled her new accessory line with BlueAvocado XO(ECO). Lauren created 20 cute food-on-the-go, travel and cosmetic accessories which are made with Repreve, a fabric made from recycled plastic bottles.

“I wanted to be part of the solution, not the problem,” Lauren told People. “As a designer, I hope that my choices can raise visibility around the importance of environmental sustainability and start to drive change with my fans. And what a great way to reuse those bottles we recycle every week.”
