Clean Warm Cotton Perfume by Clean, Relax in the embrace of the coziest new fragrance by Clean. Clean Warm Cotton is the scent of a soft blanket or a fluffy towel coming out of the dryer to snuggle up in. Rich, warm base notes of amber, musk, and fern define the heart notes of the sea, fruits, and orange blossom. Sweet and sour lemon verbena and citrus notes open the fragrance and add to its freshness appeal.
