Serge Lutens will launch L'Eau Serge Lutens, a new unisex fragrance, in March. The clean scent is meant to appeal to a wider audience than the prior scents in the line, and to do well in the Japanese market, where lighter, cleaner fragrances are preferred. Per Lutens, L'Eau Serge Lutens...
...expresses a longing for cleanliness and a reaction against society’s compulsion to fill the air with artificial scents.
L'Eau Serge Lutens is meant to duplicate "the wonderfully clean feeling that you get after a bath and slipping into freshly washed clothes".
