The top notes hit hard and you'll be smelling it for a good 45mins. Then the dry-down begins and Rien settles down to a much nicer fragrance (not that the initial fragrance is bad but to some it may be overbearing). Longevity and sillage are both very good. I still smell it after a twelve hour shift. More of a colder weather scent; although in England, you'd get away with wearing it all year round with the exception of about two weeks in the 'summer'.
