The house

More from By Kilian

By Kilian started in France in 2007 with a clear taste for boozy, sweet, after-dark perfume. Rum, caramel and vanilla run through much of the range, warmed by cinnamon and cardamom and set on patchouli, cedar or sandalwood. Angels' Share is the natural first try, warm spice and sweet woods with a glow like an old liqueur. Love Don't Be Shy is softer, sugary white flowers over vanilla. Back to Black brings honey and tobacco, and Black Phantom leans into caramel and spice. For a lighter mood, Moonlight in Heaven pairs citrus with tropical fruit.
