Like Ms. Ware, more women are forgoing scent altogether. Last year, about 15 percent of women said they did not wear fragrance, up from 13 percent in 2003, according to a survey of 9,800 women conducted by NPD.

“That may sound like a small number, but nationally that translates into two million more women who are saying ‘I don’t wear fragrance,’ ” said Karen Grant, the senior beauty industry analyst at NPD. “Eighty-five percent of women are still buying fragrance, but an increasing number tell us they are wearing fewer scents, less frequently or not at all.”

Fragrance fatigue is probably inevitable, with heavily fruited scents wafting out of everything from dishwashing liquids to hotel linens to candle displays at the mall. But perfume aversion seems to be tapping into a larger societal phenomenon that may have its origins in bans on cellphones and cigarettes: the idea that the collective demands of the public space trump one’s personal space.

“People are shying away from fragrances not for the traditional reasons that you’d expect, that it is too expensive or that they are wearing alternative products like body sprays or lotions,” Ms. Grant said. “Many people said it bothers them that fragrance has an effect on other people, that they are trying to be considerate by not overcoming others with scent.”

Indeed, Rochelle R. Bloom, the president of the Fragrance Foundation, an industry trade group, said that people who worry that their fragrance may offend others simply may be wearing perfume improperly.
