Aesop doesn't allow blue pens in any of its stores. No blue pens, no non-black pens of any color. That's the level of specificity Aesop is willing to govern in the brand. And it shows. You recognize their packaging, their stores, their products anywhere in the world. It's completely specific to itself, and the experience is controlled down to minute details.
And yet, every Aesop store looks totally different.
Their Downtown Los Angeles store was built using cardboard garment tubes sourced from the surrounding Fashion District. In Busan, the walls draw from Giwa, the traditional clay tiles used on Korean roofs. Each is a small site-specific installation, using different architects, materials, and visual logic. Every one of them is unmistakably local and unmistakably Aesop.
So how are both of these things true?
What looks like one unusually strict brand system is really two kinds of rules operating at once.
The first are expression rules. These govern the recognizable parts of the brand: no blue pens. The packaging, the labeling, the typography, the music, the sensory experience. They define what needs to remain fixed for the work to remain recognizably Aesop.
The second are decision rules. These give people a basis for making the right call when the answer cannot be pulled from a template.
For Aesop, one of those rules is to commit fully to the local context. Never be generic. You're not looking at an Aesop store template applied to Busan. You're looking at what Aesop looks like when it fully inhabits Busan.
The same logic applies beyond the retail world. A campaign can look radically different from one year to the next without losing the brand underneath it. A product system can maintain extreme formal specificity while leaving far more room for interpretation in how it shows up in the world.
The expressions don’t need to look alike. They need to come from the same underlying logic.
What most brand systems preserve
Most brand systems preserve the evidence of past decisions without preserving the logic needed to make the next one. They codify the outputs of a sensibility without ever explaining the sensibility itself.
Here are the colors we used. Here is the type hierarchy. Here is the approved layout. Here are six examples of the photography. Here is the exact amount of clear space around the logo.
All of that is necessary. But it documents the past more effectively than it prepares people for what comes next.
That works well until the brand hits something the guidelines didn't anticipate: a new channel, a new market, a new format, a new audience, a context that didn't exist when the system was created.
Without that underlying logic, teams usually default to either repetition or improvisation.
Some repeat the existing system everywhere. The work stays technically consistent, but the same choices get carried into contexts where they no longer make sense. What started as recognizability now risks becoming sameness.
Others improvise at the edge of the guidelines and start inventing their own answers. The work may respond better to the immediate context, but the brand starts to scatter. Taken together, the work no longer feels like it came from the same organization.
The alternative to rigidity isn’t inconsistency. It’s informed variation. Approved examples aren't enough. People need to understand the brand well enough to encounter something new and still make the right call.
Compliance is not coherence
Brand guidelines are very good at creating compliance. That's not the same as creating judgment. And a brand can't scale on compliance alone.
Compliance is what happens when people follow the rules they were given.
Coherence is what happens when they understand enough of the brand to make a good decision without one.
Not every rule needs to carry some profound brand truth. Some are simply operational. They make production easier, protect accessibility, maintain quality, or keep ten different teams from rebuilding the same asset ten different ways. Those rules should exist. But they shouldn't be mistaken for the whole system.
Expression rules create consistency in familiar situations. Decision rules help people navigate unfamiliar ones. Together, they allow a brand to move forward without losing what made it recognizable in the first place.The black pen still matters. But the real work of brand governance is making sure people know what the black pen is meant to preserve.
