Margo, the quiet one in velvet

Nobody quite knows what Margo is thinking, and she is happy to keep it that way a little longer. Refined, calm and slightly mysterious, she has the air of a 1950s lounge singer between sets, all dark velvet and composure. She is slim, 166 cm, her long dark brown hair straight and lacquer-glossy, her brown eyes giving away just enough. Her taste runs to vintage-inspired elegance: a velvet dress with a narrow waist, a slim satin clutch, a cocktail ring worn on the wrong finger entirely on purpose.

In her early thirties, Margo is the most composed person in any room, and wonderful company once she decides she likes you. She plays the piano, mostly late at night and mostly for herself, favouring Satie and the slow movements of Schubert. Contemporary art is her serious passion, particularly sculpture, and she gardens with surprising devotion, coaxing lavender and a stubborn fig in a sheltered patch of London soil. Her English is calm and beautifully modulated, and her rare laugh is a small reward worth waiting for.

In Mayfair she heads to Mount Street, first to see whatever is showing at the Gagosian on Davies Street, then to The Audley, the old corner pub reborn with a contemporary painted ceiling, and the dining room upstairs, Mount St. Restaurant, where the walls are hung like a private collection. She will choose a table beneath a painting she wants to discuss, order something classic and simple, and allow the night to set its own tempo.

Home for Margo is Knightsbridge; guests usually meet her a short ride away at Mount Street and around Grosvenor Square. She is resting for a few days; the booking page explains how Bella holds a date, overnights included, for her return.
