Brooklyn – Park Slope
682 Union St between Fourth and Fifth Aves
Opened by product junkie Amy Yang as an antidote to department stores, Park Slope's Luilei is devoid of overly "helpful" sales associates. The shop boasts a big sink where Yang encourages customers to test shampoos or apply masks from tester bottles--as well as a stock of hard-to-find goodies, including uncommon fragrances such as Minnie Wilde Magic and Aftelier Absinthe; cult skin-care lines like Brooklyn's own McBride Beauty and Japan's Komenuka Bijin; and cosmetics lines Hourglass and Paula Dorf.
