Amanda Holden wears perfect John Lewis summer dress

There’s one thing we know will always remain constant, and that’s Amanda Holden’s innate ability to rock a summer dress.

So it will come as no surprise that when the Britain’s Got Talent star was pictured on her Instagram feed wearing the Mandy dress (opens in new tab) from her collaboration with British fashion brand Fenn Wright Manson it was going to impress.

The gorgeous halterneck ditsy floral print dress has a flattering silhouette and a flared skirt – ideal for keeping cool in the hot weather – and while it’s understated, it’s chic enough to wear to special events as well as every day.

With a price tag of £249, it’s not cheap but as it’s the sort of summer dress (opens in new tab) you can wear for most occasions you can argue it’s a wardrobe essential.

"The Mandy is my signature shape – something comfortable, stylish and elegant that’s also flattering on the chest and waist," says Amanda.

Some of Amanda’s 1.5 million Instagram followers have expressed their delight at the Mandy, with the presenter getting more than 21,000 likes in 24 hours and compliments such as 'Beaut’, ‘Gorgeous’, 'Stunning’ and ‘My favourite dress. Already got mine.’

Amanda’s collection (opens in new tab) has been getting a lot of attention – when the actress posted a photo of herself wearing the polka dot Lily maxi dress with a handkerchief hem last week it got 17,474 likes, while the impossibly romantic Fleur dress, which Amanda calls “feminine, sassy and versatile” has already garnered more than 42,000 likes.
