According to Kibbe I'm too short to be a Natural, and am probably somewhere in between flamboyant gamine and dramatic classic if we're talking strictly about body type. I tend to do well with the "broken" lines that suit gamine types, rather than long unbroken lines (e.g. I rarely do column-of-colour looks, or long-over-lean). I do like both the Natural-Classic-Gamine and Natural-Dramatic-Gamine looks on Truth is Beauty; there's kind of a sweet spot in between the two for me -- not too prep/polished and not too punk/RATE -- that I aim for but rarely hit.
I'd never really considered colouring as an element of the yin/yang continuum; I sort of think of colour as its own distinct axis. I've moved away from high-contrast over the past year or two towards mid/low-contrast looks. I don't wear a lot of pure black or pure white anymore. With colour, I'm never sure how much my shifts are a reflection of the zeitgeist vs understanding myself better. My personal colouring is definitely lower-contrast than it used to be, thanks to growing my hair out and spending a lot of time outside. But if I chop off all my hair and go back to working mostly indoors, that will change again. Will I go back to wearing higher contrast outfits? Who knows! I do think low-contrast and tonal is also "in" right now, and I'm sure that plays a role in what I choose.
Does embracing softer colours and longer hair bring more yin elements into my style? Could be, but tempered by a lot of other yang elements: linear patterns, sturdy fabrics... I definitely think it's important to use yin and yang as a continuum, not an either/or.
The blog post about "It's a good time to be gamine" really resonates. I was totally lost when *everything* was long-over-lean. There was just nothing for me to wear! I did pretty much all my shopping at thrift stores. Then the Kamm Pants/high-rise cropped wide-leg trend came in, along with boxy tops and chunky shoes, and suddenly I could shop retail again.
