Princess Beatrice puts on a festive display in a tartan dress as she walks hand in hand with her stepson Wolfie and Edo Mapelli Mozzi at Kate’s Christmas carol concert

Princess Beatrice beamed in a festive tartan dress as she arrived at Westminster Abbey with her husband and stepson this evening.

The royal, 35, walked hand in hand with Christopher Wolfe ‘Wolfie’ Mapelli Mozzi, with her husband Edo Mapello Mozzi by her side.

Beatrice’s green and navy dress featured statement sleeves, button detailing and a flared skirt. Her strawberry blonde locks were curled and hung down her back.

Meanwhile, property developer Edo, 38, looked sharp in a navy blue suit, tie and pocket square – and Wolfie, seven, looked cute in a beige jacket with green trim and bronze buttons.

The service will recognize the selfless efforts of communities across the UK and highlight the importance of coming together to support each other.

Under Kate’s leadership, it will combine both traditional and modern elements, reaching people of all faiths.

The service, Royal Carols: Together at Christmas, will then be shown on ITV on Christmas Eve.

The service will see the world-famous Westminster Abbey choir perform some of the country’s best-loved Christmas carols, alongside musical performances from guests including Jacob Collier, Freya Ridings and James Bay, and a special duet from Beverley Knight and Adam Lambert.

There will be moving talks from speakers including Prince William, Michael Ward, Emma Willis, Roman Kemp and Jim Broadbent.

It’s been a busy week for Beatrice as she was spotted with her husband, Edoardo Mapelli Mozzi, at the premiere of James Blunt: One Brit Wonder at Picturehouse Central in London on Wednesday evening.

Beatrice exuded elegance in a velvet blazer, wool-blend sweater and satin skirt, all from Jigsaw, paired with her trusty Zara lace-up boots.

The £240 Ashby blazer comes in a striking teal shade and is designed with oversized peak lapels, contrast satin piping and horn buttons.

The couple joined a host of famous faces at the state-of-the-art cinema, along with James Blunt and his wife Sofia Wellesley.

Last Thursday, Beatrice supported her sister Eugenie at her anti-slavery charity’s first Winter Gala.

The royal perfected winter glamour, wearing her £440 black custom-made crepe and chiffon midi dress from Self-Portrait to London’s Battersea Arts Centre.

She paired the sophisticated dress, which she wore to her grandmother Queen Elizabeth’s wake, with a crocodile skin handbag and a pair of black Nicholas Kirkwood suede snakeskin pumps with a hood and toe.

Beatrice’s glamorous makeup accentuated her flawless complexion and her tresses were styled in bouncy curls.

Meanwhile, her husband Edoardo, with whom she has a daughter, Sienna, two, cut a sharp figure in an off-white linen tuxedo.

The couple both seemed delighted to be at the event together to support Princess Eugenie’s initiative, and were photographed beaming as they had their photo taken.

The Anti-Slavery Collective was founded in 2017 by Princess Eugenie and her good friend Julia de Boinville.

Through the charity, the pair have worked across various sectors to end modern slavery and also launched their podcast Floodlight, where they interview guests about the best way to end the practice around the world.

In support of Eugenie’s admirable pursuit, Sarah Ferguson was also in attendance, along with a number of famous faces.

Singer Ed Sheeran was among the guests at the glitzy event, as was James Blunt – and even Prince Harry’s ex-girlfriend Cressida Bonas made an appearance.

Eugenie’s cousin, Zara Tindall, and former British Prime Minister Theresa May (who guested in series two of Floodlight) were also among the guests.
