Meet Roja Dove, the man who makes bespoke fragrances for women who can afford to spend $40,350 to smell like no one else. His nose is so sensitive that international flights are nearly unbearable, and he compares creating his personalized perfumes to having sex.

For example, Mr. Dove had three clients smell tuberose. One gave a horrified shudder, while the other two described the scent as, respectively, “quiche with cabbage” and “young girls in tank tops running around a mall.”
