This next bit is about Volume. Of course Volume and Scale are closely related; but Volume usually refers to the larger aspects of a garment or an accessory, while Scale can be in play for a detail of them.
Extreme volume in the real world is both inconvenient, and likely to invite negative comments.
When larger Volume is handled correctly, it conveys a sense of drama, like the sweep of a floor length cape, or the delicious swing of a full skirt.
Like any of the other mechanisms I've already described, Volume rarely exists alone, the other interconnected parts affect it and it, them. For example, if a garment is a solid color, and large Volume is in use, the effect will most likely be grand and elegant looking. But render the same thing in the wrong pattern and it becomes a pile of visual noise that exhausts the eye. And if small Volume is used, and a pattern is chosen, the resulting item can seem fussy, and conservative if too small a pattern is used.
So far now, I've addressed 5 parts that make up the inner workings of Attire. There are others, like Coloration, Pattern, and Texture. I will get to these soon, so we can start looking at how they all play together. It's how they interact that makes this all so interesting, and complicated.
