Princess Beatrice Attends Her Little Sis Princess Eugenie's Wedding in a Purple Ralph & Russo Dress

The day is here! Princess Eugenie and Jack Brooksbank are tying the knot, and the crème de la crème of British society will be in attendance, including, of course, Eugenie’s older sister, Beatrice.

Beatrice, 30, Princess of York (and Queen of statement-making hats) arrived at Windsor Castle on Friday morning in a purple Ralph & Russo dress.

Eugenie’s big sis’ hasn’t been in a public relationship since her 2016 split from boyfriend of 10 years Dave Clark (who wed Lynn Anderson last summer).

Date or no date, Beatrice will have no shortage of familiar faces at the long-awaited event. She’ll be surrounded by friends and family, including her beloved cousins Princes William and Harry.

Bea looked memorably glam at both Harry and William’s weddings, too — hat game on point, of course.
