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.
A great alternative to 4711 if you don't fancy buying a giant bottle of the stuff, decanting into an atomiser and respraying every 30 minutes. A great alternative to Tom Ford's Neroli Portifino if you don't want to pay the expensive price. Not as heavy as Neroli Portifino and a bit more citrusy.
Performance: I surprisingly get about 11 hours longevity. This projects for about 2 hours and the sillage is on the lighter side of moderate. Defintely the best value out of these 3 fragrances. Big thumbs up from me!
