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.
These two perfumes couldn't smell more different. I have both. They suit different moods! Noa is creamy musk, with a hint of floral that dries down to a woody scent. Lovely is powdery, girly flowers and dries much lighter although with a hint of musk. Just sayin'
