I think Curve just might be the most misunderstood scent of all time. I own 2 bottles: one is the old Claiborne version and one is the recent EA version (though they smell remarkably similar). I've worn it for many years and as recently as this week.
Curve is mossy. It doesn't smell anything like l'homme, D&G PH, or HiM - each of which I enjoy, particularly HiM.
I'm not going to suggest it's the greatest fragrance ever made. Oh, god no. But it gets me a ridiculous amount of compliments and nothing else smells like it, which is pretty noteworthy considering the sea of sameness that is so common in men's scents. For the price, it's almost impossible to beat.
Curve often gets a bad rap from people who know the name but haven't smelled it in years and make the mistake of thinking it smells like Fierce or smells like Platinum Egoiste or who knows what else. I think a lot of the Curve flankers have a same-ness about them (sort-of), and many Claiborne scents have a drydown that is similar to Curve. Clearly, there's a Claiborne base at play. But Curve is a unique scent. Nothing else smells like it.
