What 'sillage' actually means, and why we named the site after it.
It's not a synonym for 'projection.' It's a much more interesting word than that.
The word sillage is French. Pronounced, roughly, see-yazh — though English speakers usually shorten the second syllable until it almost disappears.
In a non-perfume context it means the wake left behind by a boat. The trail in the water. What you can see of where someone has been.
In perfumery, the word's been pulled in to describe the trail of scent a wearer leaves behind them as they move through a room. It's a richer, more specific word than the alternatives — "projection" is just a measure of how loud a perfume is at arm's length, but sillage is about what's left when you've gone.
Why the distinction matters
A loud perfume can have terrible sillage. It can sit on you like a fog at one foot away and leave nothing in the room when you walk out. A quiet perfume can have astonishing sillage — a faint warmth on the air an hour after you've left, in a way that makes someone walking through say, what is that?
The two best sillage-having categories of perfume tend to be, in our experience:
- Vintage — old formulations, often from the 1950s–80s, when the materials they used (animalics, oakmoss in concentrations now banned, real sandalwood) made for compositions that radiated.
- Niche orientals built on resins and skin musks. Modern, but built like a vintage perfume would've been if you handed a perfumer 1970s materials and a 2020s sense of restraint.
If you want to feel the difference, wear something with serious sillage on a winter coat for a day, take the coat off, and walk back into the room an hour later. That's it. The smell-of-an-empty-room test.
Why we named the site after it
Because perfume isn't really for the wearer. The wearer can't smell themselves after the first ten minutes — your nose adapts. Perfume is for the wake. It's for the person who walks past you in a hallway, the friend you hug at a wedding, the seat you got up from in a restaurant.
Calling the site Sillage was a way of saying: this isn't about smelling expensive at the counter. This is about what stays in the air after you leave.
