I love the fragrances of both of these perfume, it can be used by either sex and its extremely versatile.
Ck One is one which I like to use during the day, it has a very fresh smell to it, when I use it, it makes me think of being at the ocean or rainforest. Ck Be - I prefer to use this at night as it has a lighter scent to it than the first one Ck One. It makes me think of romance and candlelight dinners under the moonlight. I would say that this fragrance is more of a romantic one.
