Popsugar Fashion Weddings Tessa von Walderdorff's Wedding Dress Paris Hilton's Brother Just Married a Countess, and the Bride's Gown Was Fit For Royalty 14 June 2018 by Brinton Parker First Published: 6 June 2018 A post shared by Nicky Rothschild (@nickyhilton) on Jun 3, 2018 at 4:01pm PDT Paris Hilton's brother Barron wed Countess Tessa von Walderdorff in a sunny St. Barts ceremony over the June 3 weekend. Her dress, which The Knot reports was a custom version of the Watters Mihr gown, had a relatively traditional skirt . . . but oh man, just wait until you see the sheer bodice and sleeves! Like good wedding guests in the Instagram era, newly minted sisters-in-law Paris and Nicky Hilton shared plenty of snaps (and Instagram Stories!) of the happy newlyweds. Other guests stepped behind the camera, too, revealing everything from the plunging neckline on von Walderdorff's gown to the convenient bustle that held up her dress while dancing. Ahead, peek every angle of the bride's gorgeous gown on her special day.
