Official souvenirs marking Princess Beatrice’s royal nuptials have gone on sale ahead of an exhibition of her vintage wedding dress.

Royal fans can buy a china tankard and pillbox, shortbread biscuits, strawberry truffles and a tea towel, with all items featuring the image of a bee – a play on Beatrice’s name to family and friends.

The princess and her husband Edoardo Mapelli Mozzi’s wedding plans were left in disarray when the country went into coronavirus lockdown in March.

The Queen’s granddaughter and her property tycoon partner were originally due to marry in May in the Chapel Royal followed by a reception in the gardens of Buckingham Palace.

But they eventually wed in a private ceremony, which was not made public beforehand, at the Royal Chapel of All Saints at Royal Lodge, Windsor on July 17, in front of just a handful of guests including the Queen and the Duke of Edinburgh.

The souvenirs are decorated with the couple’s initials and feature a floral bouquet of pink roses, peonies, lemon blossom and thistles, secured with the white rose of York.

The pink roses were blooms featured in the princess’ bridal bouquet, while the thistle symbolises the couple’s love for Balmoral the Queen’s Scottish home.

Beatrice’s wedding gown, which goes on display at Windsor Castle from Thursday, was loaned by her grandmother and was designed by Sir Norman Hartnell.

It was first worn by the Queen in the 1960s and is made of peau de soie taffeta, and features geometric hand embroidery in crystals and diamantes over the bodice, waist and hips, while the skirt is trimmed with a band of ivory duchesse satin.

It was altered for Beatrice by the Queen’s personal adviser and dresser Angela Kelly and the fashion designer Stewart Parvin.

The Queen first wore the taffeta gown for a state dinner at the British Embassy in Rome during a visit in 1961.

She also wore it to the world premiere of Lawrence Of Arabia at the Odeon Leicester Square in December 1962 and the State Opening of Parliament in 1966.

The display at Windsor Castle will also feature Beatrice’s wedding shoes, made by Valentino, which she previously wore on other occasions including the Duke and Duchess of Cambridge’s wedding in 2011.

A replica of her bridal bouquet made from artificial flowers has been created for the exhibition.

The bouquet was designed by Patrice Van Helden and contained trailing jasmine, pale pink and cream sweet peas, Royal Porcelina spray roses, pink O’Hara roses, pink “wax flower” and baby pink astilbe, as well as sprigs of myrtle in keeping with the tradition for royal brides.

Detailing how the vintage piece was carefully remodelled for Beatrice’s big day, the Royal Collection said each alteration made to the dress is reversible to preserve the historic garment.

The princess also wore a tiara loaned to her by the Queen – the Queen Mary diamond fringe tiara which the Queen, as Princess Elizabeth, wore on her own wedding day in 1947.

But the tiara will not be part of the exhibition.

Beatrice’s father the Duke of York walked her down the aisle but he did not feature in the photographs released by Buckingham Palace.

Andrew stepped down from public royal life in November last year after his disastrous Newsnight interview in which he failed to show remorse over his friendship with convicted sex offender Jeffrey Epstein.

The wedding dress will be on show at Windsor Castle in Berkshire from Thursday until November 22.
