I've found Kibbe very useful in some respects, in others not so much. I agree with what Gaylene has to say about using it as a template to understand what works for you.
Without the head to toe view it's hard to call your type, because a great deal depends on physical proportion, but if you think you're SC/SG, you probably are, because most of us can intuit what works for us as a starting point. Where Kibbe really scores, in my opinion, is in putting it all together.
When I first encountered the wacky theory on this very forum, we had a lot of fun throwing around the definitions and trying to classify ourselves. But I came away with the conclusion that two women can share the same classification and have very different personal styles. I've since paid zero attention to any visual styling guides I've found online (not for me at all) and instead applied some of Kibbe's own instructions to styling my existing wardrobe, which has helped enormously. Add to that Angie's infallible advice on body shape and you're done.
