Pippa and Kate Middleton make a glam duo at a friend's wedding this weekend

Kate Middleton caught husband Prince William's eye in a see-through dress on the catwalk at uni and now it's been revealed that sister Pippa tried her hand at modelling as a student, too.

Pippa, now 27, joined a group of Edinburgh University students for a charity fashion show in 2004.

The petite brunette - who was 20 at the time and helping raise money for a cancer charity - wore 5 different outfits by up-and-coming designers including Stella McCartney and Ted Baker.

'Pippa was a very pretty girl with a phenomenally trim, sporty figure,' a fellow student tells the Daily Mail.

'She looked great - and she knew it.'
