2002. Who's that girl? It's widely believed that Prince William first laid eyes on young Kate Middleton -- curvy in a see-through knitted mesh slip and bikini -- when she walked in a charity fashion show at St. Andrew's University. In 2011, the mesh slip sold at auction for 125,871.
Kate first caught the media's attention in March 2002 when she walked the runway in a student-produced charity fashion show wearing a sheer black sheath over a bandeau top and matching black bikini bottoms -- while Will cheered her on from the front row.
