Calvin Klein Eternity was a fragrance I used quite regularly in the mid 1990's.  I was so happy to receive a sample to test for review and revisit an old friend.  Unfortunately this is not the same fragrance I remember.  The original Eternity was a distinctive sexy, clean, floral scent that is hard to forget.  This new formula is musky, masculine and made me nauseous after wearing it for a few minutes.
