After the singer was a guest at Princess Eugenie‘s nuptials to Jack Brooksbank at Windsor Castle in October — and then performed at a festival-style event complete with a fairground and food stalls to continue the celebration the following day — Eugenie and her big sister returned the love by being close by when Goulding tied the knot with Caspar Jopling. In a unique coincidence, the wedding reception took place at Castle Howard near York Minister Cathedral — and Beatrice and Eugenie are known as Princess of York given that their parents, Prince Andrew and Sarah Ferguson, are the Duke and Duchess of York. Eugenie wore an elegant floral-print dress to the ceremony, which she paired with heels and a dark blue hat. The royal was seen arriving alongside her mother as well as Beatrice, who wore a statement-making green dress. Eugenie’s husband, who is serving as one of Jopling’s groomsmen, was also on hand, as was Beatrice’s boyfriend Edoardo Mapelli Mozzi.
