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 had statement sleeves, button detailing and a flared skirt. Her strawberry-blonde locks were curled and hanging down her back.

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

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

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

Created in a striking teal hue, the royal’s £240 Ashby blazer is designed with oversized peak lapels, contrasting 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 tailored crepe and chiffon midi dress by Self-Portrait to London’s Battersea Arts Centre.

She accessorised the sophisticated dress, which she wore to her grandmother Queen Elizabeth’s vigil, with a crocodile leather clutch bag and a pair of Nicholas Kirkwood snakeskin cap-toe suede pumps in black.

Beatrice’s glamorous make-up enhanced her flawless complexion, and her tresses were styled in bouncy curls.

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

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

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

Through the charity, the pair have worked across several sectors to help bring an end to modern slavery and also launched their podcast Floodlight, where they interview guests on how best to end the practice around the world.

To support Eugenie’s admirable pursuit, Sarah Ferguson was also in attendance – along with several famous faces.

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

Eugenie’s cousin, Zara Tindall, and fomer UK prime minister Theresa May (who was a guest on series two of Floodlight) were also among the guests.
