The Rise of Dupe Houses: How Cheaper Luxury Got Its Own Category

In 2019, Sergio Tache founded Dossier on a simple idea: tell people which luxury perfume each bottle is modelled on. Ambery Saffron says Baccarat Rouge 540 on its product page; Woody Sandalwood says Santal 33. Cheaper copies of famous perfumes are much older than that, but saying it out loud is what turned them into a category with its own shelf.

What Is a Dupe House?

A dupe house sells its own perfumes, under its own names and in its own bottles, built to smell like famous ones. The clearest ones tell you the reference: ALT’s Executive is its Aventus, Crystal No.23 its Baccarat Rouge 540. Others leave you to work it out. Lattafa doesn’t name a reference for Khamrah, though it gets compared with Kilian’s Angels’ Share.

That’s different from a counterfeit, which pretends to be the original, with the name and a copy of the bottle. And a flanker, such as an Intense or an Elixir, is the original house’s own variation.

How Is a Dupe Made?

Mostly with a gas chromatograph. GC-MS (gas chromatography–mass spectrometry) separates a perfume into its individual molecules and identifies each one, which gives a perfumer a parts list to rebuild from. It can get very close. In a Dutch case over Lancôme’s Trésor, chemical analysis found that a cheaper imitation shared almost all of Trésor’s main components.

What the machine can’t hand over is everything else. Natural materials are mixtures of hundreds of molecules, and a cheaper version may swap them for a synthetic that gets the outline but not the texture. Fragrance suppliers also patent new molecules and keep them for their own perfumers for years. They’re called captives, and nobody else can buy them. So dupes usually get the shape of a perfume right and differ in the details. Our Baccarat Rouge 540 dupes show how that plays out with a famous formula built on ethyl maltol and ambroxan.

The Four Kinds of Dupe House

Kind	Houses	What they do
They name the original	Dossier, ALT, Oakcha	Mainly sell online, with the reference printed on every product page
Middle Eastern houses	Lattafa, Armaf	Big catalogues of sweet, spicy scents, some modelled on designers and some entirely their own
Niche interpreters	Alexandria, Montagne, The Dua Brand	Go after niche houses like MFK and Le Labo, not just designer bestsellers
Oils and sprays	CA Perfume, Oil Perfumery	Alcohol-free roll-ons named “Impression of”, some also as sprays

The first group made the category respectable: clean websites, plain names and the comparison right there. The Middle Eastern houses have been around longer and work differently. Lattafa’s Khamrah is dates, cinnamon and praline, and Armaf’s Club de Nuit Intense Man sits in Aventus territory with pineapple and birch, but neither depends on a reference to make sense. The niche interpreters fill a gap the others mostly leave alone, since a Le Labo or a Roja is further out of reach than a designer bottle. The oil houses are for people who prefer to dab than spray, or who avoid alcohol.

Dossier has since moved well beyond online sales, and has announced a move into CVS stores nationwide. Dupes are now in the same aisle as the drugstore body sprays.

Are Dupes Legal?

Making a perfume that smells like another one generally is. How you sell it is where the trouble starts.

In the US, the USPTO says a perfume’s scent is functional and can’t be registered as a trademark, so nobody owns the smell of Aventus. But in Coty v. Excell (2017), a court found trademark infringement and false advertising in names, packaging and “our version of” claims, even though the products weren’t counterfeits.

Europe is stricter. In L’Oréal v Bellure, the European Court of Justice ruled in 2009 that lists telling retailers which L’Oréal perfume each Bellure scent “smelt like” were comparative advertising that presented the perfumes as imitations, which EU law doesn’t allow. The English Court of Appeal applied that in 2010, with obvious reluctance. Smelling the same was legal; saying so in that way wasn’t.

Courts even disagree on whether a scent can be owned. In 2006 the Dutch Supreme Court held that Trésor’s scent could be protected by copyright and that Kecofa’s Female Treasure infringed it. The same year, France’s highest court ruled that a fragrance is the application of know-how, not a creative work. Our guide to whether perfume dupes are legal covers the US cases in more detail.

Is a Dupe Worth It?

When you like it for itself, yes. The trap is buying a dupe as a stand-in and then spending the whole time noticing what’s missing. Take Khamrah: one reviewer loves it as cinnamon apple pie, while another wearer finds the dates and vanilla too much. Neither is judging it as an Angels’ Share copy. They’re judging the perfume, which is what you’ll be wearing.

The original is the better buy in two cases. For a gift, a bottle of Baccarat Rouge 540 sends a different message than Ambery Saffron, even if they smell alike. And for a signature scent you’ll wear every day for years, one bottle you love beats three that are almost right.

For everything else, try the dupe first. If you still find yourself wanting the original, you’ve learned something, and a sample is cheaper than a bottle. The comparisons put originals and their alternatives side by side.
