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.
Although I've not smelt the original this perfume is a lovely fresh fragrance that actually lasts all day. I've had a few compliments, just need to smell the original out of curiosity. Not bothered if it doesn't smell the same as I'm quite happy with this.
