Jules Kirby has been a fixture in the New York junior set, and for that matter, the junior sets of London and Paris, since she (and we) could remember. She’s the champagne-swilling daughter of power lawyer Roger Kirby, the boyfriend of House & Garden’s Dominique Browning, and with that, carries the notoriety of any Bryan sibling. Her mother Irène Kirby is the former French model and ballerina.

Jules herself is a former model and has done print campaigns for Calvin Klein. She was educated at Hewitt, Indian Mountain, Kent School, and NYU. She’s the quintessential heiress: a month in New York, two weeks in Paris, fall in London, skiing in Gstaad, and January in St. Barth’s, and to boot, she has residences everywhere. At 25, she’s a philanthropist and volunteer, and has particularly supported Operation Smile and Riverkeeper.

She is a part of the infamous social set of Prince Harry in London, with Harry’s hunky cousin Lord Frederick Windsor at its very helm. She is a charter member of London’s jeunesse dorée which includes such eligible bachelors as Julian Rufus Isaacs, Viscount Erleigh, Jacobi Anstruther-Gough-Calthorpe, Piers Beckwith, and Alexandre de Rothschild and such society beauties and alleged Prince-hunters as Lady Rose Innes-Ker, Lady Emily Compton, Hon. Sophia Fermor-Hesketh, Lady Victoria Hervey, Isabella Anstruther-Gough-Calthorpe, the latter of whom was the stunning blonde Prince William might have left Kate Middleton for according to the British tabloids.

Jules is also a member of the unofficial Junior International Club and has partied with Sandrine Roussel, the sister of Athina Onassis de Miranda, Tatiana Santo Domingo, Fiona and Olympia Scarry, Julia Restoin-Roitfeld, Camilla Fayed, and Charlotte Casiraghi. She is good friends with the young Monagesques as Olympia is the girlfriend of Pierre Casiraghi, and and she also counts Andrea Casiraghi as one of her friends.

And in New York, Jules is friends with Dabney Mercer and Nicole Hanley. She has been in the circuit of bright young things like Byrdie Bell, Serena Nikkhah, and Chessy Wilson through her childhood friend, Byrdie’s boyfriend Bingo Gubelmann.

Jules loves to surf and shop. Her favorite fashion houses include Chanel, Dior, and Derek Lam, and she enjoys the designs of social Tory Burch just as well. Our girl loves heels and dies for Louis Vuitton shoes.

We love Jules! She’s gorgeous, glamorous, and completely international in scope. We’re definitely going to watch her as she takes her place in New York’s blooming younger social scene.

And for her hook to Olivia Palermo (because you knew it was coming), Jules is a former friend of Olivia’s cousin Nevan Donahue. Olivia was overheard with a friend in Central Park last week saying, “I’ve had enough of this. I can’t handle any of this stuff in New York. I’m moving to L.A.” She aspires to be an actress and “pop singer” in Hollywood, where she has secured an apartment, and has written a draft for a guidebook on how to be a socialite, a la Paris Hilton, who, we’re certain, Olivia is modeling her career after.
