Fragrance notes

• Top: Iris, Shiso, Cardamom
• Heart: Tea, Suede, Patchouli
• Base: Musk, Sandalwood, Amber

Cool iris and peppery shiso open with a lift of cardamom, then soften into smooth tea and supple suede before settling on a warm amber, sandalwood and musk drydown that lingers well into the night.
