Have you ever caught a fragrance that stopped you in your tracks, and had no idea why?

Start with the family it belongs to. Perfumers sort scents into broad categories based on their core character, like gourmand, spicy, floral and beyond. Think of it as a scents version of a color palette. 

Consider this your fragrance forecast for the fall: layers. Cooler temperatures call for richer contrasts, like pairing decadent gourmands with warm woods that linger on the skin.
