Kristin Cavallari just unveiled the pink spring sandal she designed for ShoeDazzle! Called the "Bardot," the $39.95 jute-heeled wedge goes on sale May 16th, with all proceeds going to One Kid One World, a charity that provides academic and athletic programs to children in impoverished areas. ShoeDazzle will also make an additional donation of $5 for each new client that joins the site using the special code “KRISTIN,” between the period of May 1st and June 15th. “I’ve enjoyed the process of designing this unique shoe that really matches my style and personality,” Cavallari said. It looks like Lauren Conrad and Whitney Port aren't the only alums of The Hills with designer ambitions!
