Demeter Fragrance Library
How it works: Some 250 individual scents are designed to be mixed, matched and layered for unusual and individual combinations (Grass with Honeysuckle or Pure Soap with Turpentine). Even altering the order of how the fragrance goes on will affect how it ultimately smells.
What it costs: $6 for a half-ounce cologne splash, $20 for a 1-ounce spray.
