For the majority of the fragrances the longevity was quite good, from initial application to becoming a "skin fragrance ". Projection was/is about an arms length for around 4/5 hours, but can still be detected at close quarters hours after. During the dry down through to the appearance of the middle notes, the sillage is excellent, especially from the Patchouli Absolute. Because they are Parfums, an excessive amount is not required and therefore the 100ml bottles will last much longer. Will definitely be sampling others from Nicholas Charles.
