This is the most expensive bikini in the world. Actress and model Molly Sims appeared wearing a diamond bikini worth $30 million on the cover of Sports Illustrated Swimsuit. It is consists of 150 carats of D-Flawless diamonds. Designed by Susan Rosen, the bikini can best be worn only at beaches. True confession, its fall into the lingerie category is not justifiable as the fabric used for this bikini is a layer of pure diamonds and not a bit of clothe.
