Holly Willoughby wore a £1,000 designer outfit for her ‘I’m a Celebrity’ debut

With a sell-out Marks and Spencer‘s line and a daily ritual of #OOTD posts, Holly Willoughby has secured her spot as the nation’s fashion darling. But it seems the television presenter gave her high street wardrobe a designer makeover for her ‘I’m a Celebrity… Get Me Out of Here!’ debut.

Last night, the 36-year-old graced the small screen alongside Declan Donnelly for the first episode of the Australian television show and made sure her outfit didn’t go unnoticed.

Taking to Instagram to share a snap of the get-up, it turns out the mother-of-three eschewed affordable fashion in favour of an ensemble by Isabel Marant.

Embracing the summer heat, Willoughby tucked the French fashion house’s £475 ‘Mumba’ broderie anglaise top into a £510 mini skirt – also by the designer label.

In a sartorial effort to tackle the tough terrain, she finished the outfit with a pair of seriously covetable Grenson boots which weigh in at a cool £260. A £315 western-style studded belt (also by Marant) finished the television-ready outfit.

Thanks to the ‘Holly Effect’, fans soon took to the Instagram post to praise her latest look with a number lusting over her Grenson boots in particular.

One wrote, “Loving the boots Holly, you are rocking them well with the outfit!”

“You did fantastic Holly. Filling ants boots are a huge ask and you did so so well. Plus, your boots looked better,” another commented.

A third wrote: “Loved you and loved the outfit”.

But some are worried her covetable wardrobe will steal the attention from the show’s celebrities.

One took to Instagram to write: “Thought this show was about the so-called celebrities, not Holly’s wardrobe…”

After kick-starting the hashtag ‘#hwjunglestyle’, Willoughby is sure to provide fans with even more inspiration this season with three more weeks of the show in the pipeline.

Fingers crossed she demonstrates how to work her latest Marks and Spencer’s line…
