Where to go for a celebratory supper? Quaglino's, of course, which positively pulsates with glamour. Secreted away in St James', at 16 Bury Street, the sweeping staircase to the restaurant is like descending the stairs of a great ocean liner, albeit one anchored in Mayfair. For the occasion, there was only one dress to wear: a mid-century satin number weighed down with beads and pearls. A hand-made piece, purchased in Pimlico's Cornucopia (long-gone but one of my very favourite shopping haunts), this gown never fails to make me feel that I'm "Puttin' On the Ritz" - coincidentally just around the corner. Worn with brown satin heels, a deep-red vintage fur, and a statement pearl ring from Jessica Walker, plus a perfect dining companion (my daughter), in an Isabel Marant for H&M metallic dress.
