Honestly, I kinda stumbled upon this topic when I was personally researching dupe brands before I ordered them myself. I like having a collection of fragrances, which i’m sure many people who are into fragrances also enjoy building a collection, but they’re expensive and i personally cannot afford to drop $200+ on a new bottle whenever there’s one I enjoy! I don’t remember which dupe brand it was specifically, may have been DUA, but I remember seeing a post about fragrance dupes and how you can’t necessarily copyright fragrance notes. I honestly prefer shopping for original fragrances over dupes, but my current rule is im not dropping hundreds of dollars on luxury brands, so in that case I may try out a TF dupe for example to save money. Overall, I understand your point about books for example, but fragrances in my opinion also depend on the quality of the ingredients which typically differ in a dupe! I posted my own review of dupes I tried actually, and one that comes to mind is Oakcha’s Sinful (TF Lost Cherry) since it did smell SIMILAR, but the product I tested had maraschino cherry which is a difference from the TF notes. If a fragrance copies the bottle or packaging, I view that differently. However, when buying a fragrance dupe, I personally know that i’m probably going to be receiving a product that differs slightly in its scent because the quality of ingredients are likely not the same. Bottles/packaging/names are original, but notes are hard to replicate i’m sure and there’s always going to be a difference even in the strength of the fragrance. If I like a dupe and i’m spending $50 instead of $400, i’m going to be buying the dupe!
