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.
Comments:
Azzaro is NOT a replica of Aramis Tuscany. It's a fragrance in its 'own' right. For what it's worth I don't even think it resembles Tuscany in ANY way.
