Calvin Klein Eternity is a 1988 white floral EDP by perfumer Sophia Grojsman — one of the defining fragrances of the 20th century, still standing after nearly four decades as proof that great perfumery doesn't need to be updated to stay relevant. The opening is fresh and gently aromatic: freesia, sage, green notes, mandarin orange, and citruses arrive together in a clean, slightly herbal burst that's luminous and polished without trying too hard. The heart is a full, classic white floral bouquet of jasmine, narcissus, rose, lily of the valley, violet, carnation, and lily — richly layered yet balanced, feminine in the most refined sense of the word. The base of sandalwood, musk, amber, heliotrope, and patchouli closes warm, soft, and beautifully skin-close — a base that lingers for hours without ever becoming heavy. 7–9 hours, moderate projection. Best year-round — the fragrance that defined a generation and still earns compliments today.
