With the warmer weather and blue skies, it’s the perfect time to refresh your spring wardrobe – and a Hero shirt is a great place to start.

Endorsed by Catherine, Princess of Wales, and a host of famous faces including This Morning presenter Cat Deeley, it’s a versatile staple you’ll find yourself reaching for repeatedly.

Both Kate and Cat favor light blue styles and wear them with everything from casual jeans to smart tailoring, proving just how adaptable they can be.

Below, I reveal the exact pieces both women love, how to style them and – most importantly – where to buy them.

Catherine, Princess of Wales

Kate opted for an oversized blue shirt from WNU (With Nothing Underneath) on two public occasions this year.

She’s clearly a fan of the British label, as she wore the same design in white last September – which has since been worn by her sister-in-law, Meghan Markle.

The brand’s Boyfriend Shirt is celebrated for its airy shape and menswear-inspired details, with left-over-right closure in classic tailoring tradition.

It pairs seamlessly with everything from tailored shorts to a midi skirt, making it a must-have all year round.

Having personally visited WNU’s Belgravia flagship, I can vouch for its understated, effortless aesthetic and exceptional comfort.

Cat Deeley

Cat Deeley showed off her love for refined classics in a two-tone M&S shirt, teamed with wide-leg jeans, as she presented This Morning.

I love how the contrast collar and cuffs offer a fresh take on a garment.

The oversized fit and longer length mean it can be worn alone or tucked into a range of trousers, while the hidden button closure at the front provides a polished finish.

It’s the perfect mix of classic and contemporary – all for just £36.

Cat also opted for a blue cotton shirt from Boden, with a straight silhouette and a curved hem.

While the presenter paired hers with a velvet trouser suit for a glamorous look, it would work equally well for both casual and more formal occasions.

Kate previously wore a very similar Boden shirt last year, which has since sold out – making this version a great option to buy while it’s still available.
