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.
this is an exact copy and lasts just as long as the original. its £3.50 for 50ml. excellent
I found this in primark for £3.50 for 50ml. amazingly it is exactly like d&g pour femme as I have the original and it lasts the same length of time.
as the proud owner of D&G pour femme I can say this is a brilliant dupe, find it cheap on ebay but its not that widely available. if you can, buy it its great
