Side by side
Comparing the originals — price, breadth, listed-note depth.
Opens with a bright bergamot-pink pepper snap that carries real electric energy before violet leaf pulls things slightly green and cool. The heart settles into a powdery iris-orris core — clean but not soapy, with just enough lift to stay interesting. Dry-down is where it earns its price: sandalwood and ambergris merge into a smooth, skin-warm base with restrained musk underneath, projecting softly but leaving a persistent, refined sillage for hours — Best worn in cooler spring or early fall days by anyone who wants effortless, boardroom-to-dinner polish.
Opens with a dark, boozy rum that smells less like a cocktail and more like spilled rum soaking into aged wood. The tobacco arrives quickly, lending dry smokiness that keeps the sweetness from reading as candy. Through the heart, heliotrope adds a soft, powdery almond-like quality that bridges tobacco and vanilla without softening the composition into something timid. The dry-down is rich, warm, and persistent — vanilla and ambrette creating a skin-close sweetness undercut by musk. Projection is significant in the first few hours, then settles into a dense, intimate sillage that clings for hours. — Made for cold-weather evenings, date nights, anyone who wants a bold, uncompromisingly grown-up gourmand.
