Anything. My favourite so far are Cuir Pleine Fleur, Sel Marin and Cardinal but any of them worth at least a try. If you're into discreet fragrances you can't miss Heeley's creations.
CPF is apparently simple but very complex indeed, could be able to explain aerospace engineering to an infant!
Sel Marin This (together with Tirrenico by Profumi Del Forte) is what an Aquatic Fragrance should smell like in 2011. No Cool Water clones.
Cardinal Citrusy Frankincense. Transparent, confortable and absolutely compelling.
