Shannon, I was on my phone earlier and wanted to get a closer look at the photos before i replied. Now I see that everyone has already said what I would have said.
But I wanted to add some thoughts along the lines of K. Period's.
When I look at your pictures, I see a very familiar shape. (And it's not just because I look at your WIWs every day, LOL! Nor is it because we have a similar haircut -- well, until mine got butchered last week, that is -- another story for another day!)
No. It's because our shapes share some similarities. That might sound odd, since I have a strong shoulder line and you have smaller shoulders; I'm a bit taller, and so on. (K. Period has an even stronger shoulder line, and she's drawing the comparison, so obviously I am not crazy.)
Anyway...what I see is this. Structure, as others have said. You love it, you crave it, and you wear it brilliantly. Without at least some in your outfits, you feel less than fab. This has been a common theme since the beginning of your WIWs.
Then, too -- it's TAPER towards the bottom. It might be, as Sveta said, that this is your slimmest part and you like to highlight it. And you do have fab legs!
This taper, does, undeniably provide some structure. But it may also reflect a deep aesthetic preference on your part -- something relevant to that whole "style is the perfection of a point of view" comment. I don't know if I can be any clearer about that because I'm not entirely sure I understand it myself. But I do think it's worth pondering.
Anyway...like you, I love tapered skirts and pants with a structured shoulder line most of all. I do in fact enjoy my fluid wide legs -- but mine are not baggy at the top. They are snug on the top and fluid all the way past the hip. Meanwhile, my slouchy trousers and BFs are baggy/ slouchy up top -- but TAPERED down at the knee and ankle. It seems there needs to be some tailoring somewhere for it to feel or look right.
