Ck In 2U Perfume by Calvin Klein, Trendy and bursting with fresh sex appeal, Ck In 2U for women is Calvin Klein’s first gender-specific fragrance. Known for sparkling unisex scents, Calvin Klein broke with the standard to create a scent for the “techno-sexual generation.” The risk paid off in this fresh floral with a woody oriental base that ripples with erotic energy. Top notes of pink grapefruit and bergamot open the fragrance with a light, optimistic air tempered by bitter red current leaves. Avant-garde sugar orchid and cactus middle notes give way to warm, lingering base notes of amber, red cedar and classic vanilla.
