Holly Willoughby looks effortlessly chic in floral monochrome dress as she attends glitzy fashion event

Holly Willoughby looked effortlessly chic in a floral monochrome dress as she attended the Marks & Spencer Autumn Winter 21 seasonal launch event on Wednesday.

The This Morning host, 40, looked stunning in the high-necked dress, which cinched in at her trim waist and boasted statement shoulders.

The dress flowed into an elegant skirt and was paired with leather ankle boots.

Holly wore her blonde tresses in soft waves and sported a radiant palette of make-up.

The beauty was joined at the event by model Amber Le Bon, 32, who wowed in a leather dress and Lilah Parsons, 33, who stunned in florals.

 This comes after Holly accidentally promised whoever wins This Morning's Dosh On Your Doorstep competition on Wednesday that they'd be receiving a whopping £100k prize instead of the actual £1k jackpot.

A mere two minutes into the show, Holly - who presents the morning series alongside Phillip Schofield -  said: 'Alison Hammond is giving another lucky view the chance to win £100k...'

She then quickly corrected her error, saying: 'No she's not! £1k! Just £1k. What I said, minus £99k. And you're left with the correct amount. It's just £1k, which is a lot of money...'

The show then cut to Alison whose job is to surprise an unsuspecting viewer of the show with a ring on the doorbell to award them the cash prize. 

Only a shot of a brick wall was shared, so that viewers were unable to tell where the competition was taking place.

But the cameraman panned away from Alison at one point, showing the entire street beyond.

'How have the wheels come off the show at two minutes in?' Holly asked her co-host, who put his head in his hands.

Things got worse when Alison declared she needed a button resewn onto her cardigan and a random resident from the street rushed into shot to help her with it.

Neither of them were wearing a face mask and they broke social distancing, which is still being adhered to as much as possible at ITV, adding to the gaffe.

Phillip informed viewers that the presenter had broken the close contact rule during the commotion.  

'There wasn't any social distancing there at all, good Lord,' he said. 'Where's her mask? What's going on? The whole thing has fallen apart. She's doubled vaxxed though, Alison, so what can I say?' 

Later on in the show, Alison apologised: 'I am so, so sorry. I broken ITV's social distancing rules and yes I showed the street.'

Holly couldn't contain her delight as she made her grand return to This Morning following her summer break on Monday.

The 40-year-old broadcaster wore a pretty pink dress for the return after enjoying a eight week break, and proceeded to launch into a tap dance routine with her co-host Phil. 

Holly and Phillip began the show standing outside Television Centre to introduce the cast of Anything Goes, who were performing on the show - which spurred Holly to join in with the energetic dance routine.

The show is on at The Barbican in London, and said after showcasing her hidden talent: 'It's so good to be back' as Phillip roared with laughter beside her.

The author then confessed her irritation on the weather saying: 'As you can see the sun we've been waiting on all summer has decided to come back the day we go back to work.' 

After the short performance from Holly, the pair did a tour of the studio, which has been given an update while they were away.  

The COVID rules are different for the pair too, and where they once had to stay 2m apart, they can now step a little closer together to be 1m apart.

The pair, who are known to lark about on the show, even had a metre stick to ensure they were adhering to the rules. 

As Holly returns to work, so do her glam outfit updates on Instagram. 

She took to Instagram prior to the show to share a quick snap of what she was wearing.  

The candy pink dress had puffed sleeves, a huge collar and diamante buttons. 

The ensemble hugged her lithe frame as it flowed to just above her ankle. 

Elevating her figure she opted for beige heeled strappy sandals. 

Holly wore her statement blonde locks in a side parting and they fell just above her shoulders. 

She captioned the glam snap: 'Back to school! Happy Monday… see you on @thismorning at 10am…#hwstyle Dress by @ghostfashion shoes by @stevemadden.'
