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.
I'm not sure if Alta Moda are still trading. But this copy of Drakkar Noir is exceptional. It comes in a very unusual black nobbly glass flacon.The fragrance is spot-on to the original. If you can still get it I can highly recommend it.
good cheap smell a like seems to last a while too worth a punt
