Philosophy Grateful Perfume by Philosophy. Express your true self with this watery floral eau de parfum created to evoke the quality that shares its name. Worn individually grateful is tranquil and classic; paired and layered it adds an aquatic air and fluidity creating your unique signature scent. Part of the my philosophy: collection of eau de parfums designed to showcase compositions that sing one fragrance note above all others beautifully. My philosophy grateful was launched in 2015.
