Ck One Shock by Calvin Klein Perfume. Show off your most sensual side when you wear CK One Shock, the ultra-feminine women's fragrance from Calvin Klein. Released in 2011, CK One Shock offers a splash of femininity with its Mexican chocolate-infused formula. High notes of passionflower and red poppy are impossible to miss when you walk into a room. They are rounded out with sweet blackberry, the aroma of chocolate and the cooling freshness of patchouli, a freshly scented herb in the mint family.
