Fergie stuns in emerald green at daughter Princess Eugenie's royal wedding

The mother of the bride!

Sarah "Fergie" Ferguson, the Duchess of York, was all smiles on Friday morning as her daughter, Princess Eugenie, wed Jack Brooksbank in a lovely royal wedding at St. George's Chapel inside Windsor Castle.

The controversial royal arrived alongside her other daughter, Princess Beatrice, who was Eugenie's maid of honor for her big day. The adoring crowd outside of the chapel erupted as they waved upon arrival.

Fergie brought some flair to the nuptials with her chosen ensemble, opting for a vibrant emerald green dress designed by local Windsor company, Emma Louise Design. She paired the eye-catching look with a ribbon-wrapped hat and a vintage Manolo Blahnik bag.

As Express reported, her bag was carried by her late mother Susan Barrantes at the duchess's 1986 wedding to the Duke of York.

See photos of her look:

Beatrice donned a royal blue dress with a wide neckline and matching headband for her sister's wedding.

While exiting the car and before walking up the 20 steps outside of the chapel, the Duchess of York appeared to struggle with her big hat as a major gust of wind blew around her. But, ever the pro under public scrutiny, Fergie simply grabbed the brim of her hat, held it in place and continued on her way.

Also there was Princess Eugenie's father, Prince Andrew, Duke of York, who walked her down the aisle. The rest of the royal family was also there.
