While William and Catherine visited Boston for a three-day visit, the late Queen Elizabeth II's favorite daughter-in-law,

Sophie, Countess of Wessex

, attended the Royal Variety Concert at the Royal Albert Hall with her husband, Prince Edward.

They represented the family at this event for the first time.

The Royal Variety Show is a television variety show held annually in the United Kingdom to raise money for the Royal Variety Charity (currently King Charles III is the Life Patron).

The evening performance usually includes comedy, music, dance, and magic.

For this occasion, Sophie decided to wear a luxurious lace dress from the brand Erdem.

The outfit had long transparent sleeves and a laconic belt at the waist.

Sophie's hair was put up in a high evening hairstyle, and the make-up artists applied gentle make-up on her face.

According to People, the organization has been supported by Britain's reigning monarch since King George V and is believed to be the only charity in the UK with such a long and unbroken line of sovereign patronage.

According to the organization, King George V wanted members of the royal family to always attend the annual performance to demonstrate the royal family's love and support for the entertainment industry and related charities.
