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.
Got this for about €2. Wasn't expecting much but was really surprised by this. With 9 sprays you get about 7 hours with about 1 and a half hours of projection with a medium sillage. I though that I would have to douse myself to get any sort of performance! Given the mediocre performance of the original the price of this makes you question what YSL are putting in the current formulation. More linear an less complex but at the price this has to be 5/5. Just make sure you get 4-5 sprays on your clothes to prolong the top notes otherwise they can be fleeting.
Very Similar (90%) to La Nuit. Gets more similar in the drydown (95%). I get about 7 hours with this. I would say it has moderate projection. I picked this up for 7 euro in the sales. It's discontinued now but I'm certain it will make a comeback in one form or another in the future. 9/10 even at full price!
Did a review of it here:
Very nice fragrance and pretty close to the original. Performance is not beastly and just lasts 5-6 hours on my skin. But at this price, you cannot complain much.
