This particular Diptyque scent falls in the chypre category, which means it's typically composed of mossy, dry notes such as bergamot, oak moss, and patchouli. With the Diptyque Eau Capitale Eau de Parfum (£120), however, the brand puts a spin on the traditional chypre by adding touches of rose, drawing inspiration from "Parisian architecture and iconic Art Nouveau buildings." We can best describe it in one word: dreamy.
