The Princess of Wales often turns heads on public engagements with her impeccably preened hair. But in an unearthed photo shared by her university friend, Kate, now 42, looked so different.
In an unseen snap featuring fellow St Andrews student Laura Warshauer, Prince William's wife was seen wearing a cream turtleneck jumper with natural brunette curls that cascaded down her back.
These days it is a rarity for Kate to wear her hair in natural curls while out in public. Royal fans will note that she rocked her beachy hairdo during her and William's Diamond Jubilee tour of the Far East in 2012 and while on an outing in Anglesey during the couple's residency from 2010 to 2013 - but rarely again.
The now mother of three also wore a no-makeup makeup look featuring bronzey cheeks and defined eyes. "Sending love to Kate Middleton, the future Queen of England and my university dormmate!," Ms Warshauer penned in July during Kate's preventative chemotherapy for cancer which she completed in September.
"This was us at a Hope Street flat party. I have the loveliest college memories with Kate. She is the kindest, most caring, down-to-earth, genuine person, and it’s incredible to see her shining so brightly and inspiring the world with her compassion and courage."
William and Kate at St Andrews
William and Kate enrolled at the Scottish university in 2001, meeting on campus and later living together at 13A Hope Street, which cost just £100 per week each, alongside housemates Fergus Boyd and Olivia Bleasdale.
The Princess looked polished and put together in her graduation photos in 2005, sporting the traditional gown over a black pencil skirt and white fitted shirt combo.
The former Miss Middleton was spotted with her father Michael on the day of her graduation where she rocked an outfit that was perfectly in line with noughties trends but a look she could never wear as the future queen.
Prince William's girlfriend rocked low-rise jeans with a crop top and suede heeled boots with her beachy hair piled on top of her hair in a crocodile clip.
Kate's noughties style
Prior to her wedding in 2011, the royal wore a number of unusual outfits which contrasted her current wardrobe staples. Kate continued wearing low-rise jeans long after her university graduation, for example, to watch Prince Harry and Prince William play in a charity polo match at the Beaufort Polo Club in 2006.

She also loved a slinky slip dress and was spotted alongside her sister Pippa Middleton in 2011 as the pair headed to Mahiki, the ultimate It-girl spot on London's Dover Road.
