Reveal Men Eau de Parfum vs Copper Eau de Parfum

This one's a proper wild card. Some reckon it's Calvin Klein's best-kept secret - a sweet, boozy, fruity delight with surprising longevity. Others, though, find it a synthetic, syrupy mess, like a rotten fruit or a sickly sweet headache. Definitely try before you buy, but if you do blind buy and love it, you've bagged a bargain beast.

This one's a proper ride, shifting from a challenging green-metallic smack-in-the-face to a surprisingly cosy, sweet tobacco dry down. Definitely not for everyone, but if you're up for an olfactive adventure, Comme des Garçons' Copper is a unique work of art that demands your attention.
