If you're after a fresh, luxurious citrus bomb that screams 'old money' with a hint of controversy, Oligarch (or Isola Blu, if you're keeping up) is your scent. It's a high-class, super-refined take on a familiar theme, and often triggers fierce debate about whether it's truly worth the eye-watering price tag.

Nobility chases Roja Parfums' Oligarch - zesty lime, bergamot and lemon opening into blackcurrant, jasmine and orange blossom over a cedar-oakmoss-leather base. Some reviewers call it close to 95% Oligarch, if a touch more citrusy and less smooth than the original.
