Sheryl Crow is giving away her clothes, and it's all for a good cause. The songstress has launched an online auction, with proceeds benefiting Feeding America -- a cause she is passionate about.

"When I was living in Los Angeles, I started working with Feeding America on a campaign," Crow recalls to People magazine. "It's not necessarily about writing a check, it's about showing up and volunteering."

Crow practices what she preaches, frequently taking her two sons, 7-year-old Wyatt and 4-year-old Levi, to local food banks in her current hometown of Nashville, Tenn.

"After having volunteered in Nashville, you see the kind of people who come into the food bank," she explains. "It's not just homeless people, it's moms who are struggling to feed their kids; it's people who are out of work. It's a really necessary entity for a lot of people who are just trying to make ends meet."

The 52-year-old is auctioning off several items she's worn in the past, including a pair of gently used Ralph Lauren gardening boots and a black-and-white Fendi bag.

"It makes you feel so grateful to have what you have and to be able to help someone else -- the feeling that I get from that is much bigger than anything else that I could experience," Crow says. "It just matters that we take care of each other in our lives."

Crow joined RaeLynn, Jana Kramer, 50 Cent and several other celebrities at the Second Harvest Food Bank of Middle Tennessee in September, for the organization's first-ever volunteer packing event.

"I think one of the things that’s most unfathomable to most kids who grow up having a meal every morning, every noon and every evening is that’s not a God-given right," she explains. "People need to get out and volunteer and contribute money, volunteer to stuff the boxes and really show up.”

Crow's auction will run through Dec. 11. Find all of her items for sale here.
