A smell-a-like is a perfume that smells like a designer fragrance but with a different name and packaging, and at a cheaper price. A smell-a-like isn't an exact copy, but often smells very similar.
One friend has made this fragnance as a gift to me years ago! When I first smell it, it reminded me strongly of CK One. I was surprised to see, almost 10 years later that this was a dupe. It is a good imitation of CK One and I believe that if someone hasn't got a nose for perfumes maybe he won't undestand the difference and the lduration wasn't that long. I could smell the alcohol, but still for 5-6 euros it is decent. Don't forget that perfumes smell different in every person, so someone might actually thought that I was wearing CK One
