Ever wished you could shop straight from your favorite star’s closet? Now with I-Ella.com, you can. The brand new invite-only site has enlisted the help of enviably dressed celebrities like Whitney Port, who will be generously auctioning off 15 items, including the beautiful blazer she wore during the finale of her Spring 2010 show (pictured). I-Ella.com will also donate a percent of the all proceeds to a charity. In Port’s case, that means 75 percent of the proceeds go to a charity she selected, Face Africa. When you’ve shopped enough (that can happen, right?), dig around your own wardrobe. If you find designer pieces you no longer want, sell them on the site and feel good knowing your closet’s less stuffed and you’ve helped a charity. “We believe shopping can be a catalyst for social change,” says Ella Gorgla, I-Ella.com founder and CEO. “Every time you shop with us, you give back.” For those buyers who aren’t so quick to commit, you can try borrowing something you see on the site for a small fee at one-week or one-month intervals too.
