The two bids were among the highest offered for 40 items that Shakira donated to an Internet auction for her Bare Feet Foundation, which is building a school for impoverished children in northern Colombia.
Another popular item: a shiny lavender skirt with turquoise-and-coral beading that she wore while singing "Hips Don't Lie," which fetched more than $1,000.
The items were from Shakira's 2007 "Oral Fixation" tour.
Still up for grabs until Sunday: an electric Fender guitar and an acoustic Taylor guitar, both bearing the 31-year-old singer's autograph.
The auction has raised $76,000.
"It was a phenomenal success," Eric Gazin, president of Auction Cause, told The Associated Press in a telephone interview Tuesday. "We had bidders from 10 countries."
