Of the seven pure style identities, I believe Natural is the most common type - but perhaps the hardest to define.
The other types are exceptional by definition:
Dramatic are exceptionally imposing.
Romantics are exceptionally sexy.
Ethereals are exceptionally otherworldly.
Gamines and Ingenues stand out because of their seemingly eternal youthfulness and their small stature.
And Classics are unusually symmetrical and balanced.
Naturals, by contrast, are mostly defined by what they are not.
They are not visually extreme in any regard. Not extremely imposing, not extremely small, not extremely sexy, not extremely alien.
Naturals are just that - humans in their typical, average, natural state.
If Naturals get a superlative, it has to be "most friendly-looking." Even Natural supermodels look nice!
Naturals create an overall visual impression of being friendly, sturdy, and ordinary.
The attributes in a woman that tend to create this impression include:
Wait - go back a minute. Did she just call Naturals ordinary-looking?
Well, I did.
The ordinariness, the average-ness, is what makes them so appealing.
They feel familiar. We relate to them. We expect them to welcome us as fellow ordinary people.
Of course, since appearance =/= personality, a friendly-looking Natural may secretly be a right royal b****.
But that's part of the fun, isn't it?
If you're a Natural whose guileless exterior belies a devilish interior, you're twice as fascinating.
Regardless of whether or not you're the girl-next-door that you appear to be, your Natural form will be most flattered by Natural clothes: simple lines, comfortable fits, textured fabrics, functional accessories, and an overall informal vibe.
Natural or Dramatic?
Naturals can be confused with Dramatics. Both types can appear somewhat masculine. ("Yang," other writers say, but I'm trying to eschew those euphemisms.)
To distinguish between a Dramatic and a Natural, you might ask, "Does this face look friendly or threatening?"
Natural or Classic?
A Natural's ordinariness may cause her to be confused with a Classic.
An important difference between a Natural and a Classic is that Classics present an idealized version of the human average: moderate and balanced in every single dimension, without any asymmetry.
Naturals present the actual human average, which comes with asymmetries and lumps and bumps.
A test: Look at a person and imagine a cartoonist's caricature. If that's hard to do, you might be looking at a Classic. It's hard to caricature a Classic because nothing sticks out. But Naturals have plenty that sticks out.
This is why Naturals feel accessible and Classics feel aloof: Classics are so balanced that it feels almost inhuman. Naturals' "imbalances" are entirely human.
