Kate Middleton - April 2008

Just over a year after their reported separation, Kate was back by William's side in April 2008, when he received his wings upon completing his RAF training.

It was her first appearance at her boyfriend's side at a formal event since December 2006 – when she attended his passing out ceremony at Sandhurst.

And she looked every inch the princess-in-waiting, turning heads in an ivory-coloured double-breasted coat and black suede calf-length boots.
