Yes, body shapes can be confusing, we are all unique, so there is no exact standard for body shapes, but these are guidelines. You can be a mix of body shapes, though you will probably find that you fall more into one shape than another. If you have the top half of an A and the bottom of an 8, then dress them according to the guidelines for each of these shapes.
Now to answer some of your questions:
Interesting! How does the I differ from the H? They appear very similar, yet the H is advised not to belt at the waist but the I can? The real people photos really help to see the real shapes in the “raw” so to speak.
What I find the difference is that I shapes tend to have longer waists than Hs, who are also broader all over than Is.
I shapes normally feel boyish, whilst Hs feel more solid. Hs are likely to have wider pelvises and rib cages than Is.
Is are naturally very slim with narrow hips and shoulders, whilst Hs can just be very short waisted, which is why they have no defined waist, or they may even be Xs who have gone through menopause and started to carry their weight around their middle a little more, losing what was once a defined waist.
Just found this and I have to say it’s really amazing! I’m stuck between two of your shapes the V and the 8, as I have wider shoulders than hips but a high waist. Any advice?
This is more unusual, but then dress your shoulders as a V and your bottom half as an 8. Keep the shoulder broadening detail to a minimum, instead look to balance your shoulders by visually narrowing them.
You may notice that the Os are missing from the above pic, that’s because I need some good photos – don’t be shy, if you think you’re an O, send in your photo.
