The baby clothes of 15-month-old Harlow, daughter of Nicole Richie and Joel Madden, are being auctioned off on www.handmedowns.com until April 17. The auction will raise money for the Richie Madden Foundation, a charitable organization that helps disadvantaged children.

Items up for bid include tiny moccasins, Mary Jane shoes, a rainbow striped cashmere sweater, and a Ralph Lauren hoodie sweatshirt with flower lining. You can also register on the site to win a 3-piece Orbit Baby system, which includes a car seat and carrier.

Next month, movie star Angelina Jolie, mother of six, will clean out her babies’ closets and place her children’s baby clothes up for auction on handmedown.com.

The Richie-Madden Children’s Foundation was created to improve health care and education for needy children. The Richie-Madden Foundation has drawn attention to projects such as UNICEF’s Tap Project, which tries to provide safe drinking water to some of the 900 million people in the world who do not have access to clean water.
