See the TV presenter's fashion highs and lows...
Holly Willoughby is named as the face of Pretty Polly in 1999 after signing to Storm model agency.
The 18-year-old shows off her natural beauty with minimal make-up and rocks long dark hair that suits her golden complexion.
In 2004, a newly blonde Holly is almost unrecognisable when she hits the Game Stars Awards wearing a teal corset top and jeans.
Holly bags a job as the host of kids’ show Ministry Of Mayhem a few months later and appears on screen dressed in a plunging pink cami.
In the years that follow, the pretty presenter starts to really embrace her hourglass shape by covering it in fitted dresses.
A notable ensemble is the clingy blue knee-skimmer she dons for the TV BAFTAs in 2007, which she accessorises with snake-print shoes.
After securing a spot on Dancing On Ice in 2008, Holly‘s curvy chest becomes a talking point among viewers.
She’s rarely seen on the programme without a low-cut neckline.
Proving that she still can look cute even when she covers up, Holly adopts a more demure approach to fashion during her first pregnancy in 2009.
Back on Dancing On Ice later that year, Holly begins to favour fabulous floor-length pieces – she’s seen in everything from a green Grecian dress to a hip-hugging silver number.
Holly gets a little morning daring after the birth of her second child.
She reveals her wild side when she stops by the TV Choice Awards in 2011 in a tight leopard print bodycon dress.
Since then, Holly‘s had a run of style successes including the flora tea dress she fashions on The Alan Titchmarsh Show in 2012 and the red one-shouldered gown she styles with silver jewels for the BAFTAs in 2013.
