On a chilly, gray fall morning, you can slip into a hot summer day with Benefit Laugh With Me Lee Lee ($36; Sephora.com), a sunny, citrus-drenched scent of sugared lemonade and blackberry pie (there is the slightest hint of flaky crust).
A Scent by Issey Miyake ($89; department stores) is like clean, clear air blown over fields of snow and ice, carrying the scent of frozen crystals and a fresh balsam tree.
American Beauty Beloved Red Rose ($40; Kohls.com) invokes a breeze that has picked up the green notes of grassy meadows and passed through a hedge of young roses, just opening in May.
Lola Marc Jacobs ($65; Bloomingdales.com) explodes with vivid fruit. Each one seems lit up. Wearing Lola is like walking through Times Square and smelling the thousands of purple, orange, and lemon gas-plasma lights.
