Penhaligon's, the 19th century English perfume house whose classic Hammam Bouquet makes us think of rosin-warmed strings and marble Turkish baths, readies for the launch its newest scent, Iris Prima, created by Spanish nose Alberto Morillas in collaboration with the English National Ballet.
The Royal Opera House's own scent can't be too far off now.
