This fragrance is absolutely worth every, single, penny you spend on it. It is extremely sensual, very bold, intoxicating, deliciously masculine, loved by the women.
If you don't have this, get it, it's THE best fragrance.
Take the topnotes of WestSide, make it a little thicker/darker, remove the basenotes of WestSide and keep the topnotes from beginning to end then you have NdN. Simple as that. They're too similar that I do not think you need the other if you've already had one of them
