Here's the thing, cause you know, there's always a thing, always. A few days back I posted about our hard wired tendencies with regard to how we see the world around us, and the people in that world. I wanted to get inside one of those things a bit more deeply. So the thing is, physical proportional relationships.
Our minds see specific points on the body as the natural, appropriate points at which garments should begin or end.
We naturally perceive the waistline as being correct at a half way point between the nipples, and the broadest hip point. We can accept a waistline carried up to just under the breast with ease. It stays within our built in guidelines of relational rationality.
There are multiple points on the arm as well: wrist, mid forearm, elbow, mid upper arm, and armseye.
The line of the hip at its widest, and the line of the breast at the point of the nipples, are also factory installed proportion relationships we understand instantly. And as a point of clarification, all these relationships are identical for women and men, regardless of age, or culture.
So we immediately understand that all the major joining points of the body, ankles, knees, hips, shoulders, elbows, and wrists, are the correct places for garments to begin and end.
Then there's the neck. For the neck, the positional relationships are so closely packed, since its such a small zone, that staying right on point is harder. Right under the head at the top of the neck, midway between neck and trunk, base of neck, are the three localities, but they're usually separated by only an inch, sometimes less.
Ignoring these is a good deal of what lands a designer's work in the category of Avant Garde. its also a lot of why Avant Garde design is often so hard to digest. Our minds do not see the presented relationships as attractive.
