(music-news.com ) - Colombian singer Shakira is shedding her wardrobe - for a good cause. The hip-swinging pop sensation is auctioning off more than 40 articles of clothing she wore on her 2007 Oral Fixation tour to benefit her Bare Feet Foundation, which is building a school for impoverished children in northern Colombia. A shiny lavender skirt with turquoise and coral beading; a bright red dress with a plunging neckline and huge, winglike sleeves; a blue tank top emblazoned with the slogan "For Those Who Love to Rock"; and other items are up for bid on the website eBay Giving Works. The auction began on Friday and continues for 10 days. "We have bids from all over the world. It's very exciting," said Eric Gazin, president of Auction Cause, the Los Angeles company running the auction. While most auctions start out slow, bids for Shakira's clothing have already been flooding in, Gazin said. Last November, Shakira auctioned off clothing from the 2007 film Love in the Time of Cholera, for which she is nominated for a Golden Globe for the original song, Despedida.
